摘　　要：农业行走机械转向机构的性能对农业行走机械的转向具有重要影响。农业行走机械在田间使用时工况复杂多变,液压转向机构的转向力影响转向性能。通过4种不同的转向力经验公式计算分析,得出最大的转向阻力;并通过在沥青路面、水泥路面及车间对发动机不同转速及转向速度快慢进行对比试验,分析转向油缸压力的变化,为转向油缸选型及设计提供依据。The performance of the steering mechanism of agricultural walking machinery has an important impact on the steering of agricultural walking machinery.The working conditions of agricultural walking machinery are complex and variable when used in the field,and the steering force of the hydraulic steering mechanism affects the steering performance.through calculate and analyzed the maximum steering resistance of four different empirical formulas for steering force,and conducted comparative tests on different engine speeds and steering speeds on asphalt pavement,cement pavement,and workshops,the changes in steer-ing cylinder pressure were analyzed to provide a basis for selection and design of steering cylinder.
