考虑土体和方向角的某火炮0°射角动态特性分析

Dynamic Characteristic Analysis of a Certain Artillery with 0° Firing Angle Considering Soil and Direction Angle

为了研究土壤材料和方向角对轻型榴弹炮发射动态特性的影响,通过将榴弹炮放置在两种不同材料的土壤上进行有限元建模,在不同方向角下进行全炮瞬态动力学分析,得到了全炮的后坐运动特性、炮口振动特性和前座盘跳高,仿真结果为方向角和土壤材料对于牵引榴弹炮的动态特性的影响提供了重要的参考。

For the purposes of studying the influence of soil material and direction angle on the dyna- mic characteristics of a lightweight howitzer, the howitzer is placed on two different materials of soil to build the howitzer＇s finite element model. The transient dynamics analysis was conducted of the whole howitzer under different direction angles with the recoil dynamic characteristics, the vibration perfor- mance of the muzzle and the jumping height of fore attic base obtained. The simulation results provide important references for the research on the dynamic characteristics of the light-weight howitzer.
