    摘要:

    为研究实际压实工况下钢轮振动、振动液压系统压力和驱动扭矩随压实度变化的动态特性,利用ANSYS APDL建立柔性体路面模型,在Adams中进行钢轮-路面刚柔耦合动力学建模,通过AMESim与Adams建立单钢轮振动压路机振动液压系统联合仿真模型,进行不同压实度时的压实仿真。结果表明:仿真模型准确,随着压实度的增大,钢轮振动容易出现二倍频,发生跳振,振动液压系统平稳压力减小,起振时间缩短,驱动扭矩减小。

    Abstract:

    In order to study the dynamic characteristics of steel wheel vibration,vibration hydraulic system pressure and driving torque with the change of compaction degree under actual compaction conditions,the flexible pavement model was established by ANSYS APDL,and the rigid-flexible coupling dynamic modeling of steel wheel and pavement was carried out in Adams.The co-simulation model of vibratory hydraulic system of single steel wheel vibratory roller was established by AMESim and Adams,and the compaction simulation under different compaction degree was carried out.The results show that the simulation model is accurate;with the increase of compacting degree,the vibration of steel wheel is prone to double frequency and jump vibration,the steady pressure of vibration hydraulic system decreases,the vibration onset time is shortened,and the driving torque is reduced.
