digital human modeling for design and engineering - International conference and Exposition

作者： Mun, Joung H. Freeman, Jeffrey S. Rim, Kwan University of Iowa United States

Experimental analysis of human motion has been based on optical, magnetic, or electronic tracking techniques to determine body segment locations and orientations. The Average Coordinate Reference System (ACRS) method was developed to reduce experimental errors in human locomotion analysis. Experimentally measured kinematic data is used to conduct analysis in human modeling, and the model accuracy is directly related to the accuracy of the data. However, the accuracy is questionable due to skin movement, deformation of skeletal structure while in motion and limitations of commercial motion analysis systems. In this study, the ACRS method is applied to an optically-tracked segment marker system, although it can be applied to many of the others as well. Many previous studies adopted redundant marker systems, using four or five optical markers, instead of the basic three marker system to provide statistically better results of body segment position and orientation. In the ACRS method, each marker can be treated independently, as the origin of a local coordinate system for its body segment. Errors, inherent in the experimental process, result in different values for the recovered Euler angles at each origin. By employing knowledge of an initial, calibrated segment reference frame, the Euler angles at each marker location can be averaged, minimizing the effect of the skin extension and rotation. Using the proposed ACRS methodology the error is reduced when compared to the general Euler angle method commonly applied in motion analysis. Copyright © 1999 Society of Automotive Engineers, Inc.

作者： Glenn, Floyd Zachary, Wayne Le Mentec, J.C. Loiederman, Eric CHI Systems Inc. United States

This paper describes a project to investigate methods and techniques to represent physical and perceptual activity in the context of cognitive models of human performance. The application of principal interest is that of constructing computer-generated forces (CGFs) for use in large-scale distributed simulations of military forces. Of the several frameworks currently in existence for simulating human behavior at both a cognitive and behavioral level, CHI Systems' COGNET toolset represents a particularly attractive foundation for creating a tool to develop and execute CGFs. COGNET already possesses features that meet many of the human behavioral requirements of computer generated force models, including particularly its orientation toward representation of realtime, multi-tasking work environments. In this paper we describe extensions in the capabilities of the COGNET system for construction of CGF applications primarily through enhancements in the areas of sensory and motor abilities and constraints, individual differences, and situational effects. Enhancements in these areas have been accomplished through a number of extensions in which new model features have been developed using recent research results and theories. Although COGNET does not currently incorporate a detailed graphic body model, it offers a versatile tool for integrating with such models with anticipated benefits both in improving the representation of visual activities for COGNET and in providing intelligent guidance for graphic body model behavior. Demonstrations of COGNET models emphasizing perceptual and motor activities are presented. Copyright © 1999 Society of Automotive Engineers, Inc.

Virtual Prototyping (VP) is a relatively new technology which involves the use of Virtual Reality (VR) and other computer technologies to create digital prototypes. Recently, this rapidly expanding technology has matured enough to warrant serious consideration as part of the engineering design and manufacturing process. Virtual prototyping has extended beyond the specific use of virtual reality to now include the use of next-generation Computer Aided engineering (CAE) technologies including advanced visualization systems, human modeling systems, and CAD/CAM systems. The emergence of these systems has raised significant concern regarding - the integration and concurrent use of these tools. As the use of next-generation CAE systems becomes more prevalent, engineers will continue to grapple with how, when, and where to properly use these tools in the engineering design cycle. The abundance of data generated and used by these systems places considerable burden on the engineer, who often ends up spending more time on data and. process management (e.g. transferring data from system to system, version control, system integration, etc.) rather than on the actual design problem. As these systems continue to become mainstream, the burden placed upon the engineer using these systems must be alleviated. The effective use of these tools in an integrated, synergistic fashion has not yet been realized. This paper discusses a number of distinct approaches for creating a collaborative, distributed architecture for virtual prototyping. The architectural philosophies discussed include: Product Development Approach, CAE Tool Integration Approach, User-session Approach, Functional Approach, and Black-box Approach. A final architecture, created from the value-added features of each of the discussed philosophies, was created. A prototype implementation of this architecture and its underlying technological infrastructure is briefly discussed. © 1999 American Society of Mechanical Engineers

digital human modeling for design and engineering - International conference and Exposition

作者： Arlt, Frank Bubb, Heiner Technische Universität München Lehrstuhl für Ergonomie Germany

The ergonomic design of automobiles has changed over in the last years. It is increasingly being transferred from the usage of two-dimensional templates of the human shape to computer-aided manmodels. So far these models were mainly used for static anthropometric investigations on the drivers workplace. Dynamic questions can be answered only very insufficiently. In the context of this work a methodology was developed to precalculate target directed human movements in a motor vehicle environment with the CAD-manmodel RAMSIS. A new two-piece model was developed. In this model dynamic boundary conditions, so called dynamic restrictions, for any movement in a car are determined, concerning outside parameters. In the following, the entire bodyposture is determined by a statistical posture probability model, considering these dynamic restrictions. A control theory of human movements was derived from the field of neurophysiology. It was adapted to the problems for the application in a manmodel. This theory is used, to generate the necessary dynamic restrictions. For the first time, a statistical angle probability model is used to make the posture prognosis. The model was generated in a preceding work and its suitability to answer dynamic questions was validated within two test series. Altogether 12 different experiments, with in each case 15 test subjects, were carried out within all fields of this work. More than 500 "dynamic "postures were measured and analysed as well as more than 2500 movements. Within this report the developed strategy, that enables a technical designer to precalculate movements of humans within the manmodel RAMSIS realistically, will be shown. This enables the designer to regard also dynamic questions for the ergonomic design of an automobile. Copyright © 1999 Society of Automotive Engineers, Inc.

design, Automation and Test in Europe conference and exhibition

作者： E. Lauwers G. Gielen Department of Electrical Engineering ESAT-MICAS Katholieke Universiteit Leuven Heverlee Belgium

Power estimation is important for system-level exploration and trade-off analysis of VLSI systems. A power estimator for high-speed analog to digital converters that exploits information from reported designs is presented. The estimator is an analytical expression which is independent of the actual topology used and can easily be updated with new published designs. Experimental results show a good predictor accuracy of better than a factor 2.2 for most designs.

Within the development process of constructing and designing vehicles, comfort as an aspect of product quality occures to be more important. The recent developement of a new rating system, implements different aspects of scientific investigation in a multidisciplinary approach to build up an overall validation. The complex theoretical construct of comfort whith it's several aspects (i.e. postural comfort, seating comfort, thermal comfort) is split up into different criteria of evaluation. In a primary step investigation were made in order to define criteria for rating the aspects of posture comfort and seating comfort. For large persons possible deficits in design predominantly result out of the absolute size of the interior space. The limiting effects of qualitative seat characteristics predominantly surfaces in the sitting posture of small persons. These characteristics can be described by the indicator measures of the resultant and the functional knee hight, which permit a direct conclusion on the state of important body angles. The employment of six test persons in a laboratory experiment resulted in further understanding of the importance of the steering wheel position, especially regarding anthropometrical measures. The practise of the new developed rating system will show a further way to apply results of ergonomical research in the actual process of car interior construction.

For human motion studies, which are to be used for either dynamic biomechanical analyses or development of human motion simulation models, it is important to establish an empirical motion database derived from efficient measurement and well-standardized data processing methodologies. This paper describes the motion recording and data processing system developed for modeling seated reach motions at the University of Michigan's HUMOSIM Laboratory. Both electromagnetic (Flock of Birds) and optical (Qualysis) motion capture systems are being used simultaneously to record the motion data. Using both types of devices provides a robust means to record human motion, but each has different limitations and advantages. The amount of kinematic information (DOFs), external sources of noise, shadowing, off-line marker identification/tracking time, and setup cost are key differences. Although there are reports on the use of each of the devices when used separately in studying human movement, to our knowledge no research has been reported where-in both devices were simultaneously used. To meet our research goals, we believed there were advantages by combining the two devices. A kinematic linkage model, which consists of eight links and twenty-two degrees-of-freedom was developed to represent a seated operator. A protocol of placing the electromagnetic receivers and optical markers was developed considering both the kinematic linkage definition of a seated operator and the advantages/shortcomings of the two measurement devices. A simulator was built, in which typical industrial and in-vehicle reach activities could be studied. A technique to correct errors in placing the electromagnetic receivers was developed, which uses initial standardized postures. This paper also describes joint center estimation and angle calculation methods using the sophisticated human model and inverse kinematics capabilities of the EAI-Transom Jack software.

This paper addresses the problem of efficient functional simulation of synchronous digital systems. A technique based on the use of decision diagrams (DD) for representing the functions of a design at RT and behavioural level is introduced. The DD evaluation technique is combined with cycle based simulation mechanism to achieve significant speed up of the simulation execution. Experimental results are provided for demonstrating the efficiency gain of this method in comparison to the event-driven simulation.

conference on human Vision and Electronic Imaging IV

ISBN: (纸本)081943115X

The classical approach in vision research - the derivation of basically linear filter models from experiments with simple artificial test stimuli - is currently undergoing a major revision. Instead of trying to keep the dirty environment out of our clean labs we put it now right into the focus of scientific exploration. The new approach has a close relation to basic engineering strategies for electronic image processing since its major concept is the exploitation of the statistical redundancies of the environment by appropriate neural transformations. The standard engineering methods are not sufficient, however. Even a basic biological feature like orientation selectivity requires the consideration of higher-order statistics, like cumulants or polyspectra. Furthermore, there exists an abundance of nonlinear phenomena in biological vision, for example the phase-invariance of complex cells, cortical gain control, or end-stopping, which make it necessary to consider unconventional modeling approaches like differential geometry or Volterra-Wiener systems. By use of such methods we cannot only gain a deeper understanding of the adaptation of the visual system to the complex natural environment, but we can also make the biological system an inspiring source for the design of novel strategies in electronic image processing.

Computational strength determination of human long bones

Computational strength determination of human long bones

digital human modeling for design and engineering - International conference and Exposition

作者： Pellettiere, J.A. AFRL HEPA 2800 Q Street Wright-Patterson AFB OH 45433-7947 United States

With the increased number of airbags and other advanced restraint systems, the upper and lower extremities are becoming more widely studied to determine the injury potential from these devices. However, little injury tolerance data exist for whole bones. To address this deficiency, a finite element model of a female upper extremity was created from computed tomography scan data. A constant density of 1.86 g/cm3 was assumed with a previously developed transversely isotropic, elastic- plastic material model that incorporates rate effects through a modification to the longitudinal modulus and yield stress. Qualitative simulations were conducted for tension, compression, and torsion along the long axis of the bone and for three-point bending in the anterior-posterior direction. Failure was shown to occur in the area of weakest strength or greatest load. While some agreement was made with the expected fracture patterns, a greater mesh density is needed to achieve a better prediction of fracture propagation. A calculated quasi-static ultimate failure moment of 31.0 N-m for the radius and 30.8 N-m for the ulna compared favorably with data available in the literature. Dynamic simulations calculated an ultimate failure moment of 100.0 N-m for a supinated forearm and 73.0 N-m for a pronated forearm, both of which agree with previous testing. Using the methods employed here, models of human long bones can be created and used for simulations to predict strength and injury potential where testing might not be practical.
