摘　　要：为解决真空装夹炸药件加工的安全问题,对炸药件真空装夹加工过程进行三维动力学分析.综合考虑重力、离心力和切削力等因素的影响,建立静态、转动态与切削态下真空装夹安全因数的计算方法和计算公式;采用C++编程,开发安全因数计算程序,实现炸药件加工真空装夹安全性的快速、自动计算.该方法能为工艺规划与工装设计、提前预防或减少炸药机械加工中的安全事故提供参考.To solve the safety problems of vacuum clamping in explosive processing,3D dynamics analysis is performed on the processing of vacuum clamping of explosive.Considering the effects of gravity,centrifugal force,cutting force,and so on,the computation method and formulas of the vacuum clamping safety factors under static,rotating and cutting conditions are established.By C ＋＋ programming,the safety computation program is developed,by which the vacuum clamping safety factors can be calculated rapidly and automatically.The method can provide references for process planning and tooling design and help to prevent or decrease accidents in explosive machining.
