引信双球转子远解机构试验测试与仿真研究

Study on Experimental Measurement and Simulation of Fuze Double Ball Rotor Arming Delay Device

针对球转子隔爆机构延期解除保险时间较短,无法满足小口径引信延期解除保险的安全要求的问题,提出了双球转子延期解除保险技术.该装置通过定位销控制带有导向槽的球壳与球转子接力转正,实现了引信远距离解除保险的目的.试验验证了双球转子延期解除保险装置的可行性和仿真模型的合理性,利用ADAMS软件所建模型完成了双球转子装置的动力学仿真,得到了在特定弹道环境下双球转子装置的延期解除保险距离为49.455 m,满足了引信安全设计准则的要求.

Because the delay arming time of ball rotor safety device is too short to satisfy the delay arming requirement of small-caliber fuze,a double ball rotor technique is put forward.The relay rotation of the spherical shell and ball rotor is under the control of a dowel pin,which extends the delay arming distance.The feasibility of the device and the reasonableness of the simulation model were verified by experiment.The dynamic simulation of the double ball rotor device was completed by using the software of ADAMS.In a specific trajectory environment,the delay arming distance is 49.455 m,which can satisfy the requirement of safety design guidelines for fuze
