摘要:
 为了解决果园中作业机具通过性差的问题，设计一款小型抚育机履带底盘，以提高抚育机具在油茶林中的机动性和通过性。结合农用拖拉机稳定性设计的主要参数指标，基于RecurDyn动力学仿真软件建立抚育机履带底盘的多体动力学模型，开展底盘跨沟行驶过程的动力学仿真；结合设计参数及仿真试验结果，研制1台抚育机样机，并进行样机实地性能正交试验。结果表明，履带底盘的仿真试验结果与样机实地试验结果基本吻合，验证了履带底盘动力学模型的正确性；在样机实地性能试验中，抚育机林地直线行驶最高速度为1.5 m/s，当抚育机底盘质心位置横坐标为500 mm，行驶速度0.9 m/s以上时，过沟稳定性较优。
Abstract:
 In order to solve the problem of the poor generality in operation of the agricultural implements in the mechanized farming in the oil tea plantations in southern China,and to improve the maneuverability of the machine,a small high mobility crawler chassis was designed and tested.Based on RecurDyn dynamics simulation software,the multi-body dynamics model of crawler chassis of tending machine was set up,and the dynamic simulation of cross ditch process of chassis was carried out.Combined with the main parameter indexes of the stability design of agricultural tractors and simulation test results,a prototype of tending machine was developed,and field performance test of the prototype was conducted.The simulation results were consistent with the crawler chassis prototype field test results,verifying the correctness of the crawler chassis dynamic model.In the prototype field performance test,the highest speed of the tending machine was 1.5 m/s,and the stability of cross ditch was better when the chassis center position of the chassis was 500 mm,and the running speed was more than 0.9 m/s.
