| 摘 要： | 弹道簧抗力在引信高速旋转下是否发生剧烈变化是引信安全性分析的重要因素之一。采用解析法及有限元两种方法分析引信弹道簧在高速旋转状态下的力学特性，并对两种方法的计算结果进行比较。分析表明，在通常转速范围内，旋转惯性力对弹道簧变形影响很小，可以忽略。只有在转速极高时，弹道簧才会产生局部严重变形。该结论说明在一般情况下引信早炸故障不是由于弹道簧在高速旋转下抗力下降引起的。

| Abstract: | It is one of the important factors in fuse safety analysis whether tremendous change of the ballistic spring force occurs or not at high speed. The mechanical characteristics of ballistic spring under high rotation speed were analyzed by analytical calculation and finite element methods, and the results from the two methods were compared. The results show that the inertial forces have less effect on deformation of ballistic spring within a limit range of rotation speed, and the deformation can be ignored. Large deformation only occurs in the case of very high rotation speed. The conclusion shows that the reason of early burst in shooting tests is not due to the force change of ballistic spring under high rotation speed. |
