以某型迫榴炮炮闩为研究对象，基于Pro/E软件和ADAMS软件建立了炮闩虚拟样机。为了逼真地再现炮闩的工作过程，建立了复进过程中作用于后坐部分的驱动力模型、炮闩工作过程中的碰撞力和弹簧力模型。对炮闩的运动学特性以及碰撞过程开闩板与曲柄间的碰撞力、关闭杠杆滑轮与支筒间的碰撞力、关闩簧力和抽筒子压栓簧力进行了动力学仿真。将仿真结果与炮闩的实际工作过程进行对比，验证了虚拟样机的可信性。

Based on the CAD software Pro/E and dynamic simulation software ADAMS,the Virtual Prototype of a new kind of breech mechanism of mortar-howitzer gun is established. In order to recur the working process of breech mechanism,the models of driving force acting on recoil part in counter-recoil process and collision force working process of breech and spring force are founded. The kinematic characteristics of breech mechanism and the collision force between breech-opening plate and crank,the collision force between roller of closing lever and supporting sleeve,the spring force of breech-closing and the spring force of pressing-bolt are simulated kinematically. The comparison between simulation consequences and actual working process of breech mechanism validates the credibility of the Virtual Prototype.
