【摘要】 为了探索振动压路机在压实过程中的动力学特性，本文运用机械阻抗法对振动压路机－路基土壤系统的数学模型进行了分析．采用导纳伯德图可方便地识别系统的质量、刚度、阻尼、共振频率等参数，可进一步完善系统的数学模型，为压实度连续检测仪器的开发提供理论基础．更多还原

【Abstract】 In order to study dynamic properties of the vibrating roller in road compacting, the model of vibrating roller-bass soil is analyzed with mechanical impedance method. The Bode graph of mobility, the system mass, stiffness, damp, resonance frequency, antiresonance frequency are identified, and the math-model is improved conveniently. The theory is very important to develop the continuous abc-detector of the vibrating roller.更多还原
