Abstract: The analysis of dynamic behavior characteristics of vibratory rollers is the basis of parameter decision research of intelligent compaction system. However, the dynamic response characteristics under different excitation parameters and the change mechanism between different compaction stages have not been fully studied. Based on viscoelastic-plastic subgrade, a nonlinear coupling dynamic model of vibratory rollers-subgrade with 3 degrees of freedom is established in this study. By analyzing the amplitude characteristics of roller in different compaction States, the calculation index of roller compaction ability is put forward. Combined with the two-parameter bifurcation of drum, the influence of nonlinear vibration response of drum on compaction ability under different excitation parameters is studied. The results show that low excitation frequency and high excitation force are suitable for initial compaction. This is beneficial to increase the compaction capacity of the drum. In the later stage of compaction, it is appropriate to choose higher excitation frequency and smaller excitation force. This is beneficial to improve the uniformity of roller compaction amplitude and avoid vibration jumping. Non-single-cycle roller has higher compaction ability, but it may increase the impact of roller on subgrade. The calculation method of compaction capacity in this study provides a theoretical basis for the decision of excitation parameters of intelligent compaction system from the perspective of dynamics.
