摘要: 射击稳定性是超轻型火炮设计中一个关键约束条件。通过全炮发射动力学分析,研究传统结构原理火炮(A型)、采用新结构原理火炮(B型)两种后大架缓冲器布置方案对射击稳定性的影响,同时开展相应的缓冲器特性优化设计。结果表明,后大架缓冲对提高A型火炮射击稳定性效果不明显;B型火炮加装上置后大架缓冲器有利于改善后大架结构受力,提高了火炮射击稳定性。

Abstract: Launching stability is a key constraint in the design of ultra-light artillery. Through the analysis of the firing dynamics of the whole artillery, the influences of two kinds of buffer arrangement schemes on the firing stabilities of an artillery designed with tranditional structural principle (A-type) and an artillery designed with new structural principle (B-type) are analyzed, and the corresponding optimization design of buffer characteristics is also carried out. The results show that the effect of backtrail buffer on improving the firing stability of A-type artillery is not obvious; it is beneficial for B-type artillery to improve the stress on the backtrail and increase the firing stability by adding the backtrail buffer on its top.

Key words: ultra-lightartillery, backtrail, bufferdevice, hydraulicbuffer, multi-objectiveoptimization, launchingdynamics
