Flexible Multibody Modeling of Muscle Wrapping Based on ANCF and Its Applications in Human-Machine Interactions

EasyChair Preprint 13547

Abstract

The muscles wrap around their underlying bone segments in human musculoskeletal system, and the obtained curved muscle paths strongly influence their nonlinear dynamic responses. Researchers often simplify muscle wrapping as the shortest path problem without considering time-dependent muscle-bone contact. In comparison, conventional finite element method (FEM) of skeletal muscles introduces expensive computational costs. To describe nonlinear muscle-bone wrapping with acceptable computational cost, a flexible multibody modeling of the skeletal muscle was established based on absolute nodal coordinate formulation (ANCF). It was further utilized in evaluating the human-machine interactions of wearing a space suit based on forward dynamics simulations.
