摘要
建立了身管的柔性体模型,对重力作用下有初始挠度的身管振动进行了动力学仿真,并与无初始挠度的刚体身管振动的结果进行了对比。分析仿真结果并结合一般事实,说明在进行火炮发射动力学仿真时考虑身管的初始挠度是必要的。
A flex barrel model is built, and dynamic simulation of vibrations of barrel with initial defection is carried is made between vibrations of barrel with initial defection and that of rigid barrel without defection. The simulation consideration of the initial defection of barrel in simulation is necessary. out. Comparison result shows that
