摘　　要：基于ADAMS建立了以碰撞为特征的某型炮闩系统虚拟样机平台,分析了炮闩系统中关键件的磨损对炮闩动作的影响,提出了磨损失效是炮闩故障的主要模式;借助磨损试验机获得了配对材料副的磨损规律,并基于虚拟样机获得的载荷谱和运动学参量,计算出挡弹机构凸轮外廓的磨损失效寿命,填补了当前对于磨损研究多停留在实验状态,没能切实用于工程实际磨损计算的空白。This paper set up the virtual prototype platform of XX breech system featured by contact based on ADAMS, analysed the effect of a key component＇s abrasion on breech opening motion, and pointed out that the abrasion inactivation is the main failure mode of the breech. The abrasion rule of the XX material was achieved by abrasion testing machine, and the abrasion life of the cam which was one of the key components in the breech system was accounted out based on load spectrum and kinematic parameters. This work has a certain actual value.
