通过模拟试验，得出了驱动轮在砂地上行驶时的挂钩牵引力预测公式。
The predicting formula of the drawbar pull of driven wheels running on the sand is obtained by model test.
随着轮齿高度的增加，挂钩牵引力会随之增大，车轮的最大牵引效率有所降低；
The results show that when increasing the wheel load, drawbar pull accordingly increase and the tractive efficiency show downtrend before uptrend.
通过实验验证该理论模型的在预测车轮挂钩牵引力、驱动转矩及转向阻力矩的正确性。
Validity of the theory model is verified by experiments for predicting the drawbar force, steering torque and turning resistance torque.
