Abstract

Parts that come into contact with the soil are ones of the important energy consuming parts in tillage operations. In order to improve the research and development efficiency of tillage components, it is necessary to develop a performance test platform for tillage components with high interchangeability, convenience and comprehensive data collection. Therefore, a performance test platform for combined powered and passive tillage components was designed. Strength analysis and structural design optimization of key components was based on ANSYS. A real-time measurement and control software was developed based on LabVIEW platform. The related tests results show that the test platform can be used to simulate the actual condition and meet the test requirements.

Abstract in Chinese

在耕作作业中,触土部件是耕作机械重要耗能部件之一。为提高耕作部件的研发效率,需研制具有较高互换性、便捷性和数据采集全面的耕作部件性能检测平台,因此,本文研发了同时适用于主动和被动耕作部件的小型性能测试平台,基于ANSYS对关键部件进行强度分析和结构设计优化,开发了基于LabVIEW平台的实时测控软件。利用所研发的测试平台,对双翼铲和微耕刀工作性能进行试验分析。研究结果表明:1)检测平台可实时调整耕作部件工作参数并在线采集、显示与存储试验数据;2)检测平台可测试被动耕作部件耕深范围为0~40cm;对于主动开沟部件,可检测的耕深范围为0~35cm、转速在100~700r/min之间;3)双翼铲开沟器前进阻力、竖直方向阻力及侧向阻力与行进速度成正比,且侧向阻力远大于其它两方向阻力,旋转圆盘开沟器工作扭矩与前进速度成正比,所设计检测平台能够模拟实际工况,满足试验要求。
