摘要
针对我国马铃薯收获机在收获作业过程中牵引阻力大、功率消耗大和挖掘铲易损坏等问题,采用计算机模拟试验方法,建立牵引阻力数学模型,编制计算机优化设计程序,把牵引阻力模型输入计算机,从而得到土壤的理想作业环境参数。把模拟结果与试验结果相比较,分析得出误差在允许的范围内,验证了所建立模型的实用性,模型能够在一定程度上反映马铃薯收获机田间作业时的状况。
Accord to the problems of the large traction resistance,power consumption,and digging shovels which is easily damaged during the potato harvesting,this paper adopts computer simulation method to establish mathematical model,designs optimization procedure,and inputs the traction resistance model to the computer.The best working environment parameters can be obtained in soil.Comparing the simulation results with the experiment results,it is anaylised that： the model is practical in the allowed error range,,and can reflect the working condition of potato harvester to a certain degree.
