One of the commonly used bolted connections between two rotating elements is a socket set screw connection. Socket set screw connection is commonly used in couplings, between hub and gear, between hub and pulley etc. During the dimensioning of this bolted connection type dominant are two types of loads shearing and surface pressure. Especially critical cases can occur during the hole center positioning in socket set screw connections. If the hole center is moved from a given position the stresses become higher than predicted and that occurrence can lead to the connection failure. Moving the hole center makes the bolt core shear loaded section smaller and surfaces exposed to pressure smaller in one part and bigger in another part. For the purposes of this investigation, the automatic calculation algorithm has been made, which includes hole position tolerances variation. As dimensioning requirements the output torques and RPMs from standard speed reducers are taken, as well as standard coupling dimensions. Influential factors such as bolt dimension, bolt length, bolt quality, and hole position tolerances are presented. Results are given by diagram for each influential factor. The paper concludes with a discussion and further research direction in this field.

The majority of existing studies on the soil-geogrid interaction were based on the assumption that the surrounding geotechnical media was a homogeneous material. However, the different composition, structure and history of the geotechnical media resulted in significant differences in mechanical behavior. This discrepancy could lead to an overestimation of the pullout capacity of the soil-geogrid, which could in turn cause failures in the engineering practice. The influcence of the uncertainty of the geotechnical media on the pullout behavior of the soil-geogrid was investigated in this article. A number of groups of random distributions of the properties of soils, associated with the strain-softening constitutive model, were incorporated in the numerical simulation. The results demonstrated that the pullout behavior of the soil-geogrid, including the ultimate pullout capacity and the post-peak softening behavior, was highly impacted by the uncertainty of the mechanical properties of the surrounding inhomogenous media, in constrast to the case that with the homogeneous geotechnical media.

This study aims to present an approach that is specially developed for the virtual prototyping of heavy industry processes - a steelmaking plant and its melt shop. It is directed to the improvement in means of the decrease of dust pollution which is an important problem nowadays, especially for existing plants whose general modifications are expensive. The modeled process is dynamic and complex and requires a specific representation of system objects movements. The developed approach is focused on a technique that allows simulating different positions of pollution sources as well as on set up parameters of the virtual prototype and performed simulations. The study is dedicated to a detailed description of the development of the approach and its validation through comparison to real process data. The presented work is a good reference for possible simulation of models where different configurations of geometry are needed to be presented.

This article considers type synthesis and kinematic analysis of a 4R1H screw-lever linkage. This linkage combines a planar four-bar 1-DOF inverted slider-crank part and a screw one-bar 0-DOF part. Such a design allows the linkage to reproduce screw motion with curvilinear axis. This spatial motion is reproduced by the output link, when all other links have planar motion. The article provides the solution of kinematic investigation that includes position, velocity, and acceleration analysis. CAD modelling verified the obtained results of the analytical kinematics. The presented linkage might be used for robotic mechanisms in machinery manufacturing.

The cervical spine part of the dummies used in impact tests does not incorporate a fully anthropomorphic design that reproduces the neck response to an impact in an omnidirectional manner. In this work, an anthropomorphic neck is presented consisting of 7 cervical vertebrae, intervertebral discs, and springs that simulate the functioning of the muscles and ligaments, with the purpose of being implemented as a neck dummy in vehicular impacts. The experiment results show the acceleration of each vertebra in 3 planes and the angular speed experienced by the vertebra during and after an impact.

This paper presents an obstacle avoidance algorithm for a non-holonomic system consisting of a mobile robot with differential wheels. The strategy is presented and verified in simulation through two examples. The first test shows a mobile robot navigating a path where an obstacle is located, while in the second the mobile robot is fixed at a target position and an obstacle interferes. The motion planning is dynamic and the direction of the robot is changed only when the obstacle enters the zone of influence. The possibility of using a rectangular kinematic structure with a tip at the front of the robot is introduced. The rectangular structure allows to identify a contour on which to carry out distance analysis of the obstacle while the tip allows to avoid some stall situations that can occur during the robot's movements and to simplify manoeuvres to avoid obstacles. In future work, these considerations will allow the extension to a mobile manipulator composed of a base with differential wheels and a 6 degrees of freedom arm.

Energy efficiency is a challenging and relevant research field in modern manufacturing industries, where robotic systems play an essential role in the automation of several industrial operations. In this paper we present the dynamic modelling of a robotic linear axis and a method for the online optimization of point-to-point motions of the system. Exploiting the verified dynamic model of the system, the trajectories are optimized online for two different cases, namely minimum-time and minimum-time-energy, allowing the execution of sequential optimal motions without idle times. The experimental results shows the feasibility and the energy saving capabilities of the proposed optimization approach, allowing to flexibly select the best trade-off between execution time and energy consumption.

The paper presents the analytical synthesis of a symmetrical seven-bar linkage with both prismatic and revolute joints. The analytical synthesis of the mechanism shows the high variation of its stroke and height from the minimum position to the maximum position. The main reason behind why this mechanism is intended to be further used in the development of a medical disinfection robot is because its structure allows different configurations and a large height variation between its minimum and maximum position, therefore will help solving the problem of disinfecting the hard-to-reach areas from the medical environments.

The increasingly diffusion of autonomous driving has transformed the mobility framework, sparking heightened interest among both academic and industrial researchers in the field of autonomous vehicles. The main goal of this paper is the implementation and integration of path planning (PP) and path tracking (PT) algorithms to enable the vehicle to fully cross an obstacle-filled map. This technique can be adopted both in case of on-road mobility and off-road scenarios, where road natural unevenness are treated as equivalent virtual obstacles. The adopted path planning algorithm has been optimized for the generation of the shortest and best feasible trajectory based on the vehicle dynamics constraints. The resulting path is then input to the path tracking logic, configured as a Linear Quadratic Regulator controller whose design is based on a linearized vehicle model. A speed controller is also designed and implemented to improve the vehicle roll dynamic and safety. The controller is then applied to a higher fidelity vehicle model developed in IPG-CarMaker environment, thus validating the methodology through a simulation assessment approach. Optimal results confirm the efficacy of the proposed path planning and tracking strategies.

We have developed various types of walking aids. However, the required functions differ depending on the target audience and their purpose. On the other hand, based on the results of past clinical experiments, we have confirmed that assisting only the ankle joint affects the movement of the entire leg. We believe that this is due to the chain reaction of stretch reflexes in the bi-articular muscles. Based on these results, we are focusing on assisting ankle joint movements during walking. However, depending on the target audience, from patients to healthy individuals, the required assistance force, degree of freedom, and means of assistance also differ. We have created several pieces of hardware that are easy for patients or elderly people to handle, prepared various auxiliary means, and presented the results of comparisons.
