Analysis and Simulation Study on Agricultural Machinery Hydraulic Priority Steering System
Abstract：To study the response of the agricultural machinery priority steering system and its influencing factors, this paper analyzes the working principles of the dynamic and static priority steering systems of agricultural machinery. A system simulation model was established based on AMEsim, and the steering performance of the dynamic and static priority steering systems was compared. The influence laws of dynamic damping, LS feedback damping, and CF feedback damping on the dynamic priority steering system of agricultural machinery were studied. The priority of the steering system was analyzed, highlighting the importance of the priority valve. The research results show that compared with the static system, the dynamic priority steering system has a faster response; the priority of the steering system is higher than that of the lifting system; when the passage of dynamic damping increases, the response of the dynamic steering system increases; when the passage of LS feedback damping increases, the response of the dynamic steering system is delayed; CF feedback damping has no effect on the steering system.
