为了分析制造误差和装配误差对动力伺服刀架保持器精度可靠性的影响，对刀架精度可靠性灵敏度进行了研究。首先介绍了动力伺服刀架保持器的精度可靠性模型。给出了可靠性摄动法的灵敏度分析理论。然后，将该方法应用于型号为SFW 25的动力伺服刀保持器的可靠性灵敏度分析，得到了制造和装配误差对精度可靠性的重要性排序。为提高所研究的动力伺服刀架保持器的精度可靠性提供了指导。
To analyze the effect of the manufacture and assembly errors on the accuracy reliability of power servo tool holder, the accuracy reliability sensitivity is investigated in this work. The accuracy reliability model of power servo tool holder is introduced firstly. The sensitivity analysis theory of the reliability perturbation method is given. Then, the method is applied to the reliability sensitivity of the power servo tool holder of which the type is SFW25 and the importance order of the manufacture and assembly errors for the accuracy reliability is obtained. It offers the guide for improving the accuracy reliability of the considered power servo tool holder.
