弹丸膛内运动姿态动力学仿真

Simulation of Dynamic for Motion Attitude inside Pill Chamber

在Solidworks中建立了较精确的线膛炮身管模型及其他部分的实体模型,导入机械系统动力学分析软件ADAMS中进行了装配和约束,形成了弹丸发射的动力学模型。利用ADAMS软件进行了二次开发,建立了内弹道解算的模块,应用ADAMS软件中的位移、速度等函数,以状态变量的形式建立了反后坐装置的力元,模拟了弹丸在膛内的运动过程,得出了弹丸膛内的运动姿态,在该模型的基础上可以进一步对全炮的发射过程进行动力学仿真。

Based on the software of Solidworks,it built more accurate model of line chamber pipe and entity model of other parts,and introduced them into ADAMS to make assemble and restrain,then the dynamic model of pill launch formed.The paper made the secondary development for software of ADAMS and built the module of inner ballistic trajectory calculation.By means of function such as displacement,velocity and so on in software of ADAMS,it built the force unit of reverse recoil mechanism in form of state variable,simulated the pill motion process inside the line chamber pipe,and obtained motion attitude in chamber pipe.Based on the above model mentioned,it could make the dynamic simulation for whole launch process.
