温度对火炮反后坐装置工作性能影响数值仿真

Numerical Simulation of Temperature's Influence on Gun Recoil System Service Behavior

温度对火炮后坐装置工作性能影响十分复杂,基于某型火炮的内弹道和反后坐装置后坐反面问题模型,采用数值仿真方法,系统分析了装药温度、驻退机温度、复进机温度单个变化和同时变化对火炮后坐阻力和后坐长度的影响。研究表明:装药温度和驻退机温度变化对火炮后坐阻力和后坐长度影响较大;火炮首发射击和连续射击时,后坐阻力峰值和后坐长度与温度之间并不是单调的增减关系;火炮连续射击可以达到更为苛刻的极限射击条件。

The effect of temperature on the working performance of artillery recoil is very complicated. Based on certain gun＇s internal ballistics and recoil system reverse problem models, numerical simulation method is used to analyze the each change and total changes of powder, recoil mechanism, recuperator temperature＇s effect on gun recoil system service behavior. The research indicates the temperature of powder and recoil mechanism have greater influence on gun＇ s recoil resistance and recoil length, the relations between the recoil resistance peak and the temperature, the recoil length and the temperature are not monotonous when gun first firing or continuous firing, the harder extreme fire conditions are reached when gun continuous firing.
