摘要: 振动压路机振动轮的动态行为特性分析,是智能压实系统参数决策研究的基础。然而,不同激励参数下的动力学响应特性以及不同压实阶段间的变化机理尚未得到充分研究。本研究基于粘弹塑性路基,建立了3自由度的振动压路机-路基的非线性耦合动力学模型。通过分析振动轮不同压实状态的振幅特征,提出振动轮压实能力的计算指标。结合振动轮的双参数分岔,研究不同激励参数下振动轮的非线性振动响应对压实能力的影响。结果表明,压实初期适宜选用较低的激励频率和较大的激励力。这有利于增大振动轮的压实能力。压实后期适宜选用较高的激励频率和较小的激励力。这有利于提高振动轮压实振幅的均匀性,以及避免跳振现象。非单周期运动状态的振动轮有更高的压实能力,但这可能会增加振动轮对路基的冲击作用。本研究的压实能力计算方法,从动力学角度为智能压实系统的激励参数决策提供了一种理论依据。

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.
