摘　　要：基于系统键合图模型,利用20-SIM仿真软件,对六自由度转台的一个支路进行了建模与仿真。从仿真结果可见,采用动压反馈是提高和产生恒定阻尼的较好办法,因其可明显提高系统阻尼比,并且不改变系统开环和闭环刚度,进而扩展系统的频带,提高控制精度。Based on the key matches diagram of system, made use of 20-SIM imitation software to construction model and imitation for a byroad of six free degree rotation stand. That adopted power press feedback was better way to improve and produce permanently stable damper from imitating result. Power press feedback can improve damper ratio of system apparently and cant change the stiffness of open the wreath with shut the wreath of system, proceed to the next step to expand frequency band of system and increase control accuracy.
