摘　　要：某型履带式步兵战车配备有新型自动装弹机,但在使用过程中发现其故障率相对较高,其中开关等元件所引起的故障占比较大。不同于以往,该型自动装弹机采用新型非接触式接近开关替代接触式开关,而接近开关主要用于传递装填关键信号并控制供输弹动作。以某型履带步兵战车输弹机为例,结合虚拟样机技术,利用MSC.Adams建立旋转输弹机的动力学模型,通过分析关键点的动力学特性和振动响应,探究接近开关造成输弹机故障的具体原因,为维修保障提供参考依据和相关支撑。A new type of auto-loader is equipped with one type tracked infantry fighting vehicle.However,in the actual using process,it is found that the auto-loader has a relatively higher failure rate,and the failure caused by switch has a larger proportion.Different from the past,this type of autoloader adopts several new type of non-contact close switches,which is to replace contact type of switches.The close switch is mainly used for transmitting key loading signal and controlling feeding and ramming actions.Taking ramming mechanism of one type tracked infantry fighting vehicle as one example,combined with virtual prototyping technology,via the analysis of motion characteristic and vibration response of key marker,it explores the reasons of ramming mechanism failures caused by close switches,which is able to provide foundation and support for maintenance.
