摘要
针对履带车辆机动性实验教学要求,设计了测量履带板与可变形地面的动态加载附着力的实验系统。实验系统包含动态垂向加载系统、水平牵引系统和数据采集装置,利用电液伺服激振台的垂向加载特性设计了可实现高加载速率、重载荷的垂向加载系统,采用蜗轮丝杠升降机和减速机设计了可调速率的水平牵引系统。实验表明,该系统操作简单,实验工况真实有效,可以满足高频重载工况下履带板与可变形地面之间的附着力测量需求。
According to the requirements of the experimental teaching of tracked vehicle mobility, an experimental system is designed to measure the dynamic load adhesion between the track shoes and the deformable ground. The experimental system consists of dynamic vertical loading system, horizontal traction system and data acquisition device. The vertical loading system with high loading rate and heavy load is designed by using the vertical loading characteristics of electro-hydraulic servo vibration excitation platform. The horizontal traction system with adjustable speed is designed by using worm screw elevator and reducer. The experimental results show that the experimental system is easy to operate and the experimental conditions are real and effective, which can meet the requirements of adhesion measurement between the track shoe and the deformable ground under high frequency and heavy load conditions.
