Triangulations for surface scattered points are used in the field of three-dimensional reconstruction widely. In order to reconstruct surface fast and efficiently, a combination triangulation algorithm was proposed. The triangulation method includes three steps: firstly, the scattered points were carved into many regions by the Axis-Aligned Bounding Box algorithm, then searched k-Neighbor points of each scattered points and constructed its tangent plane, transformed 3D triangulation into 2D triangulation. Secondly, direct triangulation were carried out according to the criterion of different side rule; the angle of two normal vectors maximized rule; the threshold distance rule of semisphere and the internal minimal angle maximized rule. Finally, each region were connected or spliced by 3D Delaunay circumsphere rule. Experiment results shows that the combination algorithm can triangulate the scattered points precisely and efficiently.

The wave bearing developed by Dimofte in the 1990's features a continuous wave profile and presents numerous advantages compared to plain journal bearings. One of the main advantages of the wave bearing is that it has a higher degree of stability than the plain journal bearing and this load capacity is close to the load capacity of the plain journal bearing. Predicting these coefficients for the wave bearing with high bearing numbers is difficult, although there are many studies on the aerodynamic bearing. This paper presents an analytical method for calculating the limiting values of load capacity, dynamic stiffness and damping coefficients of the wave bearing for compressible fluids by simplifying the compressible Reynolds equation at high journal operation speed. A computational method is submitted which is derived from simple algebraic equations combined with infinitesimal perturbation method. The limiting characters of the wave bearing are compared with the plain journal bearing for all eccentricity ratios. Special emphasis is placed on investigating the effects of wave number, wave eccentricity ratio and wave starting angle on the limiting characteristics. Numerical results obtained indicate that the load capacity and stiffness of the wave bearing is better than the plain journal bearing at the same eccentricity ratio. Copyright © 2014 by ASME.

This paper presents an improved method to teleoperate impedance of a robot based on surface electromyography (EMG) and test it experimentally. Based on a linear mapping between EMG amplitude and stiffness, an incremental stiffness extraction method is developed, which uses instantaneous amplitude identified from EMG in a high frequency band, compensating for non-linear residual error in the linear mapping and preventing muscle fatigue from affecting the control. Experiments on one joint of the Baxter robot are carried out to test the approach in a disturbance attenuation task, and to compare it with automatic human-like impedance adaptation. The experimental results demonstrate that the new human operated impedance method is successful at attenuating disturbance, and results similarly to as automatic disturbance attenuation, thus demonstrating its efficiency. © 2014 Springer International Publishing.

In the recent years haptic interfaces became a reliable solution in order to solve problems which arise when humans interact with the environment. If in the research area of the haptic interaction between human and environment there are important researches, a innovative approach for the interaction between the robot and the environment using haptic interfaces and virtual projection method is presented in this paper. In order to control this interaction we used the Virtual Projection Method where haptic control interfaces of impedance and admittance will be embedded. The obtained results, validated by simulations assure stability, stiffness, high maneuverability and adaptability for rescue walking robots in order to move in disaster, dangerous and hazardous areas.

High-speed couplings are the key parts of micro-turbomachinerys. They are assembled to shafts by interference fits, which can transfer large torque, are easy to produce and offer significant cost advantages. Considering of the influences of the torque, rotational speed and temperature variation, the interference fits between couplings and shafts have to be analyzed accurately in order to save the construction cost and reducing risk of invalidation accidents. In this paper, a model of the interference fit between a coupling and a shaft is developed to study the determine parameters of the interference value. Using the classic elastic plane stress theory, the exact solutions of the radial stresses, hoop stresses and radial displacements are obtained. Three determine parameters (the torque, angular velocity and temperature variation correction terms) are derived in order to calculate the interference value. Taking a high-speed microturbomachinery for example, the numerical results show that the interference value is dependent of the ratios of inner radius to outer radius of the coupling and shaft significantly. The torque, angular velocity and temperature variation correction terms are in the same order of magnitude. The present analytical solutions are expected to be useful in the structure design of the interference fit between a high-speed coupling and a shaft. © (2013) Trans Tech Publications, Switzerland.

In order to detect the tool-substrate contact force and the tool-target interaction force during nano-manipulation process, a novel MEMS based 2D piezoresistive micro-force sensor structure was proposed. This structure can realize the 3D hardware decoupling for the X,Y and Z axis. Thus, the force detection in the vertical direction (Z axis) and parallel direction reference to base (X axis) can be done simultaneously. Theoretical analysis shows that this structure has a good structural sensitivity. The rationality and feasibility of the structure were confirmed by simulation results. © 2013 Trans Tech Publications Ltd, Switzerland.
