某舰炮后坐力作用时间对动力放大系数影响研究

Study on the Influence of a Naval Gun's Recoil Action Time on Dynamic Magnification Coefficient

为保证舰炮发射安全,需对舰炮基座及加强结构进行强度校核,而动力放大系数是校核中不可或缺的元素。以ABAQUS为基本工具,以改变后坐力增长持续作用时间及后坐力作用持续时间为基本方法,分析研究了舰炮在极限工况下不同后坐力作用时间对动力放大系数的影响,基于仿真结果提出了校核过程中部分改进方法。

In order to ensure the safety of na-val guns,strength checks must be performed on the base and reinforcement structure,and the dy-namic magnification coefficient is an essential ele-ment in the check.Based on ABAQUS,by chan-ging the recoil growth duration and recoil duration of action as the basic method,the impact of recoil action time on the dynamic magnification coeffi-cient in extreme conditions is analyzed,and sug-gestions for improvement on some of the strength check procedures are proposed based on simula-tion results.
