基于虚拟样机的两自由度柔顺机构设计与仿真分析

摘要/Abstract

摘要： 为满足精密导向与大运动行程的设计需求，设计了一种基于柔顺机构的两自由度工作平台。描述了平台的设计方案，从理论上推导了工作方向上的刚度特性；为便于机电联合设计仿真，利用ANSYS和ADAMS软件建立了虚拟样机模型，对工作平台的刚度和工作行程进行了仿真计算。实验结果表明，平台工作方向上的刚度远小于非工作方向上的刚度，满足精密导向要求，线性行程超过了4mm，满足行程设计要求。

Abstract: In order to meet the requirements of precise linear guide and a large travel distance, a two-DOF compliant mechanism was designed. The total design proposal was introduced and the characteristics of stiffness in the working direction was analyzed. For the further co-simulation in mechanical and electrical system, a virtual prototype model was established based on ADAMS and ANSYS to verify the designed stiffness and linear distance of the two-DOF compliant mechanism. The test results show that the stiffness in the working direction is much smaller than that in other directions, which meets the demands of precise guides. The linear distance is longer than 4mm, which meets the demands of distance of travel.

Key words: compliant mechanism with two-DOF, characteristics of stiffness, finite element, virtual prototype
