论文题目：拖拉机电液控制三点悬挂耕深稳定性试验研究

摘要：在现代农业装置的设计研发过程中,土槽试验台可以模拟田间不同含水率及坚实度的土壤的耕作情况,能够不受农田环境、驱动设备震动和天气等外部因素的影响进行农机化实验,从而缩短新型农业机械自动化产品的研发与投产周期,对推广现代化农业技术具有重要意义。本文针对某农业工程研究所研发的土槽试验平台,设计开发了一套土槽试验平台自动控制系统,完成了平台系统的测试工作,该系统具有很好的测控精度和稳定性,可开展不同类型农业测试试验。本文主要研究如下:（1）土槽台车系统硬件方面的设计与实现:根据台车系统工作特点与原理,设计了行走装置的传动系统并阐述了液压装置各个部件的作用。同时,根据装置的往复运动特性设计了滑触线供电系统和配电系统来保证装置获得稳定安全的电源,根据其动作惯性大且负载大的特性给变频器设计相应的制动电阻来满足安全要求。（2）土槽台车系统软件方面的设计与实现:分析了台车试验的自动控制流程,同时对电液悬挂系统的力调节和位调节分别分析了其在实际工况下的利弊,并采用力位综合系数的方式将两种方式结合,将力位综合控制调节转换为对油缸位移的模糊控制,使用西门子Siemens S7-1200PLC作为控制器。建立模糊控制模块,最后对得到的实验结果进行分析。（3）实现上位机登录与监控界面:采用西门子Siemens WINCC7.3组态软件开发上位机监控系统,设置工程师与操作员用户权限,采用手动模式与实验模式来满足不同的控制要求,设计了数据报表与曲线界面,完成数据保存与报表打印功能和实时监控数据的变化情况,有利于进行实验分析和控制优化。（4）研究分析了耕作机具的拉力分布与农业机械电液三点悬挂的关系。使用土槽台车和四铧犁完成了耕作试验的全因素设计。使用SPSS软件分析了从实验中获得的数据。
