Hexapod型隔振系统的建模与仿真

Modeling and Simulink of Hexapod Vibration Isolation System

以Hexapod压电智能主动隔振平台系统在航天器高精度隔振和定位中的应用为基础,建立了Hexapod型隔振平台的虚拟样机。用MATLAB设计了控制系统,并介绍了控制系统的控制算法。通过MATLAB与ADAMS的结合,对Hexapod压电智能隔振和定位系统进行了仿真,得到了该隔振平台在低频(2-50Hz)时的隔振仿真结果,结果表明了该系统在航天器低频隔振上的有效性。

Research on the Hexapod piezoelectric vibration isolation system, build the controlling and dynamic simulation method of mechanism system using virtual prototype technique and use the MATLAB software to design the control system, and then combine the MATLAB and ADAMS to get the simulation result about the vibration isolation condition about 2-50 Hz are presented. The result shows the validity of the system on vibration isolation which is used on the astrovehicles.
