摘　　要：常规的线性尺寸链计算方法可以用于液压马达的公差分析,但忽视了形位公差对于液压马达装配精度产生的影响。通过运用公差原则,考虑液压马达中形位与尺寸之间的关系,决定形位公差的增减性,利用蒙特卡洛模拟法随机抽样进行计算机模拟,模拟实际表面的偏移,验证形位公差对尺寸链的影响。Conventional linear dimension chain calculation method can be used for tolerance analysis of motors,but the influence of shape and position tolerance on assembly accuracy of motors is neglected.By using tolerance principle and considering the relationship among shape,position and size in motor,the increase or decrease of the shape and position tolerance is determined.Monte Carlo simulation method is used to simulate the displacement of real surface and verify the influence of the shape and position tolerance on size chain.
