摘要
研究对火炮动力学性能设计方法的优化,准确的设计方法对火炮系统的研究具有很重要的意义。现行的火炮后坐部分膛内时期动量计算方法得到的结果与火炮试验中得到的数据存在很大差异。为提高计算的准确性,对现行计算方法进行优化,提出了一种新的后坐部分动量计算方法。为验证新方法的优越性,建立基于弹炮耦合的某舰炮后坐部分模型,利用ABAQUS有限元分析软件对该舰炮后坐部分膛内运动时期进行仿真分析。结果表明,新方法与仿真结果吻合度较高。数值仿真结果可以为相关研究提供参考。
To study the optimization of artillery dynamic performance design method,Accurate design method of the study of gun system has very important significance. The momentum data for recoiling parts during the projectile motion in the bore,which is obtained by a artillery test,have obvious difference compared with the calculated results.In order to improve the accuracy of the calculation,and optimize the current calculation method,this paper proposes a new took some momentum calculation method. In order to verify the superiority of new method,a projectile-barrel coupling model for a certain naval gun has been set up and the simulation analysis for the movement during the projectile motion in the bore has been carried on through ABAQUS. The simulation results show that the new method on momentum calculation for the recoiling parts during the projectile motion in the bore is accurate. Besides above,the results can provide a reference for correlation study.
