INTRODUCTION Most everyday activities, performed over a long period leads to performance degradation of skeletal muscles as well as spinal column which is reflected in the reduction of maximum force, reduction of the speed of response, reducing control of the movement etc. Although until now many mathematical models of muscles are developed, very small number takes into account the fatigue, and...

In accordance with the fundamental principles and methods of Human-Computer Interaction (HCI), this paper has explored the design process and methods on modeling technique of furniture equipment through studying the computer-aided modeling design of modern furniture products; and builds up a complete set of 2D and 3D sketch design system through demonstrating the transformation of furniture pro...

This research estimates the high-cycle fatigue (HCF) life of integrated concrete bridge installed on water due to temperature changes. To this end, CATIA software was used geometrically model a real-scale bridge. Next, thermal–structural coupling analysis performed by finite element (FE) simulation in ANSYS WORKBENCH software. The comparison technique with experimental data validate simulation....

In this study, a graphic simulator that is used to simulate problems related kinematics and dynamics for an exoskeleton robot arm with 5 degrees of freedom (DoF) was presented. The utilized the advantages design software SolidWorks, Catia, computing simulation power SimMechanics Toolbox in Matlab. core proposed algorithm solve dynamic developing upper-limb rehabilitation robot. study optimizati...

Production cars are designed to understeer and rarely do they oversteer. If a car could automatically compensate for an understeer/oversteer problem, the driver would enjoy nearly neutral steering under varying operating conditions. Four-wheel steering is a serious effort on the part of automotive design engineers to provide near-neutral steering. Also in situations like low speed cornering, ve...

OBJECTIVES The objective of this study was to investigate the effect of chain installation condition on stress distribution that could eventually cause disastrous failure from sudden deformation and geometric rupture. METHODS Fractographic method used for the failed chain indicates that over-stress was considered as the root cause of failure. 3D modeling and finite element analysis for the ch...
