摘　　要：为了提高小型两行轮式玉米收获机在复杂地形的作业能力,设计了一种三点调平装置,建立了调平模型并对其进行了理论分析,并设计了调平控制系统。在此基础上,设计并制造了试验用车,对倾角信号进行滤波处理后,进行了调平试验。试验结果表明:车身左倾最大调平角度是15°,右倾最大调平角度是17.5°,前倾最大调平角度是12.5°,后倾最大调平角度是17.5°,验证了自动调平机构和控制系统的可靠性和实用性。设计的针对4YZ-2玉米收获机的三点调平装置和调平控制系统可为玉米收获机自适应调平提供了研究基础,并为其他行走农业机械的调平设计提供了新思路。In order to improve the operational capability of a small two row wheeled corn harvester in complex terrain,a three-point leveling device was designed,a leveling model was established,and theoretical analysis was conducted.A leveling control system was designed.On this basis,a test vehicle was designed and manufactured,and the inclination signal was filtered and processed before conducting leveling tests.The test results show that the maximum leveling angle for the left tilt of the vehicle body is 15°,the maximum leveling angle for the right tilt is 17.5°,the maximum leveling angle for the front tilt is 12.5°,and the maximum leveling angle for the rear tilt is 17.5°.This verifies the reliability and practicality of the automatic leveling mechanism and control system.The three-point leveling device and leveling control system designed in this study for the 4YZ-2 corn harvester provide a research foundation for adaptive leveling of the corn harvester,and provide new ideas for leveling design of other walking agricultural machinery.
