Dynamic Analysis of the Mechanism with Joint Clearance [PDF]

open access: yes, 2015
随着工业水平的不断发展,含间隙机构的动力学及其控制的研究逐渐成为了一个热门课题。由于间隙的存在对机械机构的动力学特性造成了一定的影响,所以分析运动副间隙的影响对于机械机构设计和优化的意义就显得十分重大。本文中主要是以具有代表性的含间隙曲柄滑块机构和机械手臂机构为例,来分析间隙以及柔性因素给机械机构动力学特性带来的一些影响。 建立了机械系统的动力学方程,为含间隙机构动力学分析研究提供了理论基础;分析了基于弹簧阻尼模型的Impact接触碰撞函数,为研究轴与轴套间的接触碰撞过程提供了理论依据 ...
