摘　　要：随行式人力转向飞机牵引车运动时人车互相作用，特别是在转向过程中，各处的运动都在变化。以液压驱动无杆飞机牵引车为研究对象，研究人机之间的运动特性，测试操控适宜速度范围，考察不同速度对人员操作的影响，以及人员随行所能承受的最高速度；通过对试验测试数据曲线的对比分析，了解极值速度发生时牵引车的运动状态。结果表明：操控该车适宜速度在6 km／h以下，最高极限车速是11 km／h，左右极限摆动变角度转向速度高于极限定角度回转速度，变角度转向时人的行进速度高于车速。The operators, who control the vehicle in manual, walk follow the vehicle and control the movement direction of vehicle and they interact with each other. Everywhere sport changes especially during the process of manual steering. Taking the aircraft tractor driven in hydraulic mode without towbar as the study object, the motion characteristic between the operator and tractor is studied, the suitable speed range is tested, the influ- ence of moving speed to operation is examined and the maximum speed that person can bear is investigated. The motion state of the tractor in extreme velocity is found through comparing and analysis on test curve. Result shows that the appropriate speed for handling the vehicle is below 6 km/h, and the maximum speed limit is 11 km/h. The speed of steering the vehicle swings from the left to the right limit at different angles is higher than the speed of rotation at constant angle, and the speed of operator is higher than the speed of the vehicle.
