摘　　要：针对生姜收获机长时间田间作业,而轮式拖拉机和机械传动式履带拖拉机普遍存在作业时稳定性差、功率小、作业时间短的问题,设计一种履带自走式生姜收获机的底盘液压系统,该机械以液压驱动作为动力源,通过履带底盘的液压回路实现整机的直行、爬坡和转向,以达到生姜收获机有效行驶和作业的目的。首先对液压系统元件进行计算选型,然后通过AEMSim软件完成仿真模型的搭建,组成完整液压系统,最后,对该系统分别进行直线行驶、纵坡上坡和原地转向3种工况的仿真验证。液压元件的仿真结果表明选型符合计算要求,液压系统设计合理,可以保证生姜收获机直行行走平稳、稳定爬升16°及以下坡度的硬土路面,能够按照实际转向要求完成转向过程。For long-term field operations of ginger harvesters,wheeled tractors and mechanical transmission tracked tractors generally have problems such as poor stability,low power,and short operation time during operation,The chassis hydraulic system of a tracked selfpropelled ginger harvester was designed,which used hydraulic drive as the power source.Through the hydraulic circuit of the tracked chassis,the entire machine could achieve straight travel,climbing,and turning,in order to achieve effective driving and operation of the ginger harvester.Firstly,the hydraulic system components were calculated and selected,and then the simulation model was built using AEMSim to form a complete hydraulic system.Finally,the system was simulated and verified under three working conditions:straight driving,uphill longitudinal slope and turning in place.The simulation results of the hydraulic components showed that the selection met the calculation requirements,and the hydraulic system design was reasonable,which could ensure that the ginger harvester travels straight ahead smoothly,climbs steadily up hard soil surfaces with gradients of 16°and below,and was able to complete the steering process in accordance with the actual steering requirements.
