Abstract
In ergonomics, biomechanical models are used to analyze stresses imposed on the musculoskeletal system. To conduct dynamic analyses, data regarding the motion of the body must be collected. If successfully developed, motion simulation can be used in place of the collection of joint coordinate data. A two-dimensional whole-body lifting simulation model is presented in this paper. Using an optimization concept, manual lifting motion is generated to satisfy an objective function subject to various constraints including limitations in kinetics and kinematics and those imposed by the physical layout of the task. Examples on the formulation of the constraints are given. Results of the simulation indicate that it is possible to improve the predicted motion by incorporating more realistic constraints provided that a reliable mathematical optimizer is available.
