履带式军用工程机械推土作业时悬挂闭锁策略研究

摘要

For tracked engineering vehicles, to analyze the effects of different suspension locking schemes on dozing capability, a mechanics model of the vehicle during crowding and lifting is set up, and the relation of the penetration loads and lift forces in different suspension locking schemes to the vehicle attitude is analyzed then. A virtual prototype model of the vehicle is created by using ADAMS/ATN software, and the cutting and blade lift processes in different suspension locking schemes are simulated numerically.The results show that the scheme of locking the first, the second and the sixth pair of loading wheels can improve the dozing capability of the vehicle greatly.%为分析履带式军用工程机械不同悬挂闭锁方案对推土作业性能的影响,文中以某履带式工程车为对象,建立了推土铲刀向下推压和向上提升过程的力学模型,分析了采用不同闭锁方案铲刀推压力和提升力与车体姿态的变化关系,并利用ADAMS/ATV模块建立了虚拟样机模型,对采用不同闭锁方案的切土过程和提铲过程进行了动态仿真,分析结果表明:闭锁该履带式工程车第1、2、6对负重轮的悬挂对提高推土作业性能效果最佳.研究方法和研究结果为履带式军用工程机械悬挂闭锁方案的确定提供了理论参考.
