一平移两转动三自由度减振平台的动力学分析
Kinetic analysis of parallel vibration-absorber platform with 3-DOF of one translation and two rotations
摘要
Abstract
A novel 3-DOF parallel mechanism platform with one translation and two rotations was designed to improve dynamic performance of mechanical and electrical products and ensure the accuracy of the original products under multi-vibration working conditions. The theoretical Jacobian matrix formula of the platform was analyzed to calculate the real Jacobian matrix of a specific position. According to the theoretical results of Jacobian matrix, the modal analysis of the parallel vibration-absorber system was a-chieved to obtain the natural frequency of the system. The three-dimensional model of multi-dimensional parallel damping platform was built by Adams software to obtain the transmission rate of the system. A prototype of multi-dimensional vibration-absorber system was manufactured to measure the transfer function. With theoretical result of 4. 089 2 Hz, simulating result of 4. 219 Hz and testing result of 4. 6 Hz, the results show that the designing theory and analytical method of the vibration are reasonable.关键词
