摘　　要：为了更加深入研究半固定管道式喷灌系统移管机 ,对其运动的确定性进行了论证 ,并对其运动性质和动力特性进行了分析计算。通过分析移管机的运动情况 ,得出了加速、匀速、减速过程中的运动方程 ;通过受力分析 ,得出了加速、匀速、减速过程中作用于行走轮的外加牵引力。In order to research thoroughly on pipe_moving machine of half_fixed_pipeline sprinkler irrigation system, its movement certainty is demonstrated, and its movement property and kinematical characteristics are also analyzed and calculated. Through analysis of the movement property of pipe_moving machine, the kinematical equations of acceleration, even speed and deceleration are deduced; through bearing_force analysis, exterior tractions acting on working wheels in the processes of acceleration, even speed and deceleration are calculated.
