舰炮射击击发装置损坏故障定位研究

Research on location of damaging fault of percussion mechanism in naval gun firing

某舰炮击发装置在射击实验中,多次发生击发装置损坏故障,具体表现为击发装置推杆被撞弯,导致射击停止。通过故障树分析方法,对故障的各末端因素进行逐一分析,并确定推杆动作不灵活和磁铁顶杆螺栓防松不可靠是击发装置多次损坏故障的主要原因。解决方案中对磁铁顶杆螺栓防松措施进行调整,并对击发推杆机构进行改进,并进行多次实弹射击实验,彻底解决了舰炮射击时击发装置损坏的故障。

The damaging fault of percussion mechanism was usually occurred in the naval gun firing of a new model,the result is that the percussion mechanism putter is bent,causing a stop of firing,the end factors of the fault are analyzed one by one through the method of fault tree analysis,it is determined that the main reasons for the damaging fault of percussion mechanism are the looseness of the putter and unreliability of the electromagnet bolts.In the solution,the anti loosening measures were adjusted and the push rod mechanism of percussion mechanism was improved.On the basis of several practical firing experiments,it is completely solved the damaging fault of percussion mechanism in naval gun firing.
