A distributed approach for access and visibility task under ergonomic constraints with a manikin in a virtual reality environment

Abstract

This paper presents a new method, based on a multiagent system and on digital mock-up technology, to assess an efficient path planner for a manikin for access and visibility task under ergonomic constraints. In order to solve this problem, the human operator is integrated in the process optimization to contribute to a global perception of the environment. This operator cooperates, in real-time, with several automatic local elementary agents. The result of this work validates solutions brought by digital mock-up and that can be applied to simulate maintenance task.

Inverse dynamics method using optimization techniques for the estimation of muscles forces involved in the elbow motion

“…One of the solutions to improve the working conditions is to estimate and analyze muscle forces developed by a human during its work tasks. This estimation is a good way to improve the ergonomics [2], because of the tools that can be used to perform the analysis [10]. Our goal is to test ergonomics of working stations by analyzing the muscle forces in a virtual scene.…”

One cabin equipment location method based on the visibility human-factor potential field

“…Yin adopts visual cone method to assess the visibility of manufacturing process [12]. Bidault combines the method of clipping plane and visual cone [3]. In order to increase the design and analysis efficiency of the space layout design, the model based on visibility optimization design method is indispensable, but there are very few relative studies at present.…”
