Experimental analysis of friction performance requirements and influencing factors of composite anti-skid pads

为解决装甲车进出坞舱过程中的打滑、侧移问题,对装甲车与坞舱甲板湿摩擦接触面滑移运动过程进行理论分析,确定了装甲车装载过程中所需要的临界滑动摩擦系数;根据装甲车进出坞舱运动状态及衬垫服役环境,完成了衬垫结构设计,在考虑多种影响因素下,制备了16组衬垫试样进行摩擦性能测试,依此确定了最优衬垫方案,其湿摩擦系数可达0.87,质量磨损量为0.284 g。

In order to solve the problem of slipping and side movement during the process of armored vehicles entering and exiting the docking bay, this paper conducts a theoretical analysis of the sliding motion process of the wet friction contact surface between the armored vehicle and the docking bay deck, and determines the critical sliding friction coefficient required during the loading process of the armored vehicle. According to the movement state of the armored vehicle in and out of the dock and the service environment of the liner, the liner structure design was completed. After considering various influencing factors, 16 sets of liner samples were prepared for friction performance testing, and the optimal liner plan was determined accordingly. Its wet friction coefficient can reach 0.87, and the mass wear amount is 0.284 g.
