Multibody Dynamics Integrated With Muscle Models and Space-Time Constraints for Optimization of Lifting Movements

摘要: A multibody dynamics model integrated with space-time constraints based optimization is presented in this paper for generating optimal trajectories of human lifting movements. “Space-time constraints” a two-point boundary value dynamic technique developed animation computer graphics characters and has significant potential biomechanics other mechanical movement problems. Optimization results demonstrate the ability to consider different preferences minimizing loading specific joints such as an ankle, or knee, shoulder during motion resulting are shown be different. Lumped muscle models generate joint torques incorporated at five actuation effects muscular system movement. The then on activation parameters instead traditionally used torques. correlate better actual tests conducted by VICON video capture test data analysis system.Copyright © 2005 ASME
