摘要
为了解决传统仿真平台无法同时模拟低频大幅摇摆运动和高频小幅振动的问题,提出一种可同时模拟高、低频运动,能承受重载并具有运动参数实时监测功能的多频振动仿真平台。首先,确定并分析仿真平台的构型;其次,根据动平台的位姿反解建立调姿平台和隔振平台的位姿,求解获得滑块和电动缸的位移;再次,建立并联6-PUS仿真平台一、二阶影响系数矩阵,分析解决速度和加速度;最后,给出机构的数值仿真算例。
In order to solve the problem that the traditional simulation platform can not simultaneously simulate the low-frequency large-sized rocking motion and the high-frequency small-amplitude vibration, this paper proposes a multi-frequency vibration simulation platform with the function of bearing heavy load and real-time monitoring of motion parameters, which can simultaneously simulate high and low frequency motion. Firstly, the configuration of the simulation platform was determined and analyzed. Secondly, the pose of the attitude adjustment platform and the vibration isolation platform was established according to the inverse displacement analysis of the moving platform, and the displacement of the slider and the electric cylinder was obtained. Then, the first and second order influence coefficient matrix of the parallel 6-PUS simulation platform were established to analyze the speed and acceleration. Finally, the numerical simulation example of the mechanism was given.
