扭力矩对曲折槽保险机构动力学响应影响分析

在考虑扭力矩作用的基础上，建立曲折槽保险机构的动力学模型，以某机构为计算实例，与传统的动力学模型进行比较。数值计算结果表明：引信跌落到硬质地面时，扭力矩的影响作用不明显，而跌落到松软地面上时扭力矩使惯性简的位移响应明显增大，不能忽略。其结论为判断长储引信勤务处理意外跌落的安全状态提供了理论参考。

Dynamic Response Analysis of Twisting Force to Zigzag Slot Arming Device

On the basis of considering the effect of twisting force to zigzag slot arming device, the dynamics model is established,and a certain device is simulated as an example and is compared with the orthodox dynamics model. The numerical simulating results show that the twisting force has no apparent effect on the dynamic response while the fuze is dropped on hard ground, but if dropped on soft ground it has an obvious effect and this effect can not be ignored. This provides the theoretical reference for estimating the safety state of the long-term storage fuze when it may be dropped on the ground accidentally.
