The People

Moving independently is very important for people with walking disability, thus, in this paper the novel walking assistance device is designed based on strategies derived from optimization of available walking assistance devices for ‎the people with walking disabilities. Available walking assistance device like ReWalk has high price and heavy weight disadvantages. Therefore, the main aim of this study is optimization of available devices by new design and analyses to make them cheaper and lighter. The presented device is a simulator of a human body motion in lower limb which consists of ‎ hip, shank and knee. All parts were designed and assembled in software module and after manufacturing, it could be used as a rehabilitation device for the people with walking disability to support their sitting, standing and walking. As a result, regarding to aforementioned issues, in this study the new walking assistance device was designed which is inexpensive and light weight.

Anybody Modeling System

Main causes for discomfort experienced by vehicle drivers during driving were investigated using a rigid-body model originally developed in the AnyBody Modeling System [. The interactions between the human body and the car-seat in various combinations of seat-pan/backrest inclinations and the effect of pedal spring stiffness were analyzed using an inverse dynamics approach. To deal with the muscle redundancy problem, (i.e. the problem with the human-body containing more muscles than necessary to drive its degrees of freedom) a minimum-fatigue criterion [ was utilized. The results show that various seat adjustments (e.g., seat-pan and backrest inclinations) and the pedal spring stiffness have complex influences on the muscle activation and spinal joint forces of the human body. From the results, an optimal adjustment for the car-seat is proposed, i.e. the backrest inclination is 10° and the seat-pan inclination is between 0o to 5 o. This study can in general capture the overall interactions between human body and environment (i.e. the maximum muscle activity and spine forces), which is thought to be the factors of driving fatigue.
