摘要
高精度隔振平台所受的环境微振动干扰是复杂的.因此研究了隔振平台动力学和主动控制方案,对复杂振动环境下采用电磁力控制的高精度隔振平台作了计算机仿真.根据仿真结果,比较了平台系统各参数对平台主动和被动隔振效果的影响.
The dynamical analysis and computer simulation of the isolation platform controlled by electromagnetic forces with high accuracy are carried out. The vibration environment included basement vibration, periodical variation of tide generating force of the sun and the moon, movment of test equipment on platform and other transient shock. According to simulation results, the effects of the variation of mass, stiffness and damping of the platform system on active isolation or passive isolation are analyzed, and the effects of the variation of parameters in active control on vibration isolation are also analyzed.
