摘要
基于工件的准静态受力分析 ,运用经典Hertz接触理论 ,计算夹具 工件接触区的变形。根据多刚体运动学 ,建立表面加工误差和接触变形的关系 ,对加工误差进行预报。此方法也可用来计算定位基准误差对加工误差的影响。
It is very important to study contact area's deformation between workpiece and fixtures Based on the quasi static force analysis of the workpiece,Hertz theory is used to calculate the deformation According to the multiple rigid body kinematics,the relationship between the contact deformation and surface machining errors has been established,so that machining errors can be predicted This method can also be used to analysis the machining errors caused by fixture locating error.
