对单钢轮振动压路机在振动压实时前轮附着力变化的原因进行分析，并据此设计相应的试验。试验结果表明，低频高幅振动时总牵引力明显减小，且在1挡和3挡工况时钢轮出现打滑现象。提出振动压实时前轮有效附着系数的概念，并给出计算公式，根据试验数据计算出在振动压实时有效附着系数约为静压时的46％，并且通过理论分析得出在2挡时附着系数利用率最高。可为振动压路机参数设计和工程应用提供一定的参考和依据。

In order to be convenient for engineering calculations,the relative experiment is designed after analyzing the reasons why the adhesion force on the front wheel of the single vibratory road roller changes in the process of vibratory compaction.According to the result of the experiment,there is a significant decrease in the total traction force when the frequency is relatively low and the amplitude is relatively high and there exists a slipping phenomenon in the first gear and third gear.And then,a concept of effective adhesion coefficient is put forward and its calculation method is provided.The effective adhesion coefficient calculated by experimental data in the process of vibration compaction is about 46 percent of the adhesion coefficient in the process of static compaction.Finally,a conclusion is drawn that the utilization rate of adhesion coefficient is highest in the second gear.It is hoped to provide some reference and basis for the parameter design of vibratory roller and engineering applications.
