粘弾性体を含むマルチボディシステムの高速かつ安定な動力学解析手法の検討

抄録

Since a multibody system including viscoelastic bodies is a stiff system, stable analysis is difficult with ordinary explicit numerical integration. In this research, we try to develop an approximate analysis method that can analyze the system including the viscoelastic body at high speed and stably by combining the approximate rigid link model, the recursive dynamics algorithm, the linear viscoelastic model and the implicit numerical integration method. In this paper, we explain the case where the Voigt model or Maxwell model is used as the linear viscoelastic model.
