摘要
针对防风固沙横向草方格铺设机在起伏不平沙漠表面作业的位姿调节需求,设计一种电液控制位姿调节悬挂系统,用于连接防风固沙横向草方格铺设机与拖拉机。分析位姿调节悬挂机械机构,建立运动学模型;设计位姿调节液压系统,建立阀控缸液压动力元件模型;设计电液控制系统方案。采用AMESim软件建立横向草方格铺设机位姿调节悬挂仿真模型。仿真结果表明:电液控制系统设计可行;横向草方格铺设机位姿调节悬挂设计可行。
To meet the posture adjustment requirements of the wind proof and sand fixation transverse grass grid laying machine when operating on uneven desert surfaces,we design an electro-hydraulic control posture adjustable suspension system for connecting the wind proof and sand fixation transverse grass grid laying machine to the tractor.The mechanical structure of the posture adjustable suspension is analyzed,and a kinematic model is established;a hydraulic system for posture adjustment is designed,and a valve-controlled cylinder hydraulic power element model is established;and an electro-hydraulic control system scheme is designed.A simulation model of the posture adjustable suspension of the transverse grass grid laying machine is established using AMESim sof tware.The simulation results indicate that the electro-hydraulic control system design is feasible;the posture adjustable suspension design for the transverse grass grid laying machine is feasible.
