摘　　要：以虚拟样机为基础,分析了并联机构中虎克铰的误差对机床机械误差的影响,分别得到了当虎克铰在3个方向上单独存在误差时对机床动平台的影响,以及3个方向同时存在误差时对机床动平台综合位置精度的影响。Based on the virtual prototype,the effect of Hooke＇s Joint error on the position of working platform of parallel machine tool is analyzed in the paper. The study is about two conditions,one kind of situation has the error in one direction,another kind of situation has the error in three directions.
