多点摩擦接触问题的离散动力学模型及数值求解
Discrete Dynamics Model and Numerical Solution for Multiple Friction and Contact
摘要
Abstract
Aiming at multi-rigid-body with multiple friction and contact,a multi-rigid-body dynamics model expressed by complementary equations was firstly given.Secondly,dynamics models for multi-rigid-body with multiple friction and contact were discretized into a discrete mixed nonlin-ear complementary model for application of computer simulation based on fixed time-stepping meth-ods.Thirdly,aiming at solution problem for mixed nonlinear complementary model,the mixed non-linear complementary model was changed into a linear complementary model to resolve by Coulomb friction approximation methods and simplification methods of equality constraints.Finally,the validi-ty of the dynamics model for multi-rigid-body with multiple friction and contact and its numerical solution method was verified through a numerical example.关键词
