柔顺机构PR伪刚体动力学建模与特性分析
Dynamic Modeling and Characteristic Analysis of Compliant Mechanisms Based on PR Pseudo-rigid-body Model
摘要
Abstract
Based on the pseudo-rigid-body model ( PRBM ) , a PR pseudo-rigid-body dynamic model ( PRBDM) subjected to a force at the end was developed considering the effects of transverse deformation and axial deformation of flexible elements in compliant mechanisms comprehensively. The dynamic equation of the PR PRBDM was derived by using the Lagrange equation. The changes of performances of the PR PRBDM were showed in the equation feature and dynamic responses. The numerical analysis results indicate that the PR PRBDM proposed can be used to show the real dynamic characteristic of compliant mechanisms by introducing a prismatic pair to simulate the axial movement of flexible elements in compliant mechanisms and was suitable for the dynamics analysis and design of compliant mechanisms.关键词
