摘要
为了能够更准确方便得到主被动混合隔振系统的特性与设计参数,利用虚拟样机技术对主被动混合隔振系统进行了主动控制仿真研究。首先,对主被动混合隔振平台进行了理论计算与模态分析;然后,通过ADAMS软件创建了混合隔振平台的虚拟样机,并将其导入至MATLAB/SMULINK中搭建了主被动混合隔振系统,通过变步长法对主被动混合隔振系统进行了次级通道辨识,并在此基础上基于多通道Fx-LMS算法进行了主被动混合隔振的效果分析。仿真结果表明:利用虚拟样机技术对主被动混合隔振系统进行主动控制取得了较好的控制效果,为主被动混合隔振物理样机的设计与制造提供了新的思路与方法。
In order to acquire more accurate characteristics and design parameters of the active-passive isolation system,the virtual prototype of active-passive hybrid vibration isolation platform is established and simulated.Firstly,the theoretical calculation of model isolation platform and the modal analysis is carried out.And then the virtual prototype of the platform is established through ADAMS and the active-passive hybrid isolation system is built by MATLAB/SMULINK.The identification of second path of isolation system is carried out through variable step size method.On this basis,the isolation effect is discussed in detail based on Fx-LMS algorithm.The simulation results reveal that the active-passive hybrid vibration isolation system achieveds a certain degree of control effect using virtual prototyping technology,which represents a new concept and method for the design and manufacture of physical prototype.
