摘要
直接采用贝氏理论及其派生方法预测驱动车轮在沙地上重复通过时的牵引性能将会产生较大的误差。本文参照试验结果提出了减小这种误差的可行途径。应用本文的方法，可明显改善刚性驱动轮在松散沙土上重复通过时牵引性能的预测精度。
It has been shown by allalysis that to predict the multi-pass performallce of a driven wheel on sand with Bekker's theory will result in a larger error. A practical method to reduce this kind of error, according to the experiment results. has been presented in this paper, and with it the multi-pass performance of a rigid-driven wheel on sand can be calculated satisfactorily.
