Abstract
For improvement of the operation performance of vehicle operation
equipment, it is important to consider mechanical characteristic adaptability of operation
equipment with human musculoskeletal system at the early development stage.
We have developed the evaluation technique (analysis of manipulating force at hand) of
mechanical characteristic musculoskeletal system by combination manipulating force
ellipsoid, one of manipulability evaluation techniques of robotics, and the computer manikin.
The musculoskeletal system has been modelled 3-dimensional 3-link 7-joint model
considered characteristics of joints´ torque.
Developed technique performed well in study on quantitative analysis considered
characteristics of joint´ torque, qualitative experiment of muscular load analysis at the
operation of door and the operation performance development of a door system.
These results suggested potential of this technique for muscular load analysis and
effectiveness of consideration of mechanical characteristic musculoskeletal system described
by manipulating force ellipsoid (analysis of manipulating force at hand by this technique) for
improvement on operation performance of operation equipment.
