ADAMS二自由度振动压路机验证分析

ADAMS-Based Validation of Vibratory Roller Having Two Degrees of Freedom

为验证现有振动压路机-沥青路面系统二自由度动力学模型的可靠性,运用ADAMS软件建立沥青路面、偏心块、振动压路机虚拟样机模型,确定合理路面刚度值,得到振动压路机位移、速度、加速度响应图,以及改变路面刚度值后所对应振动压路机各参数的变化图.通过分析各参数影响图形变化趋势,对比实际情况中各参数的影响,可知该理论研究与实际情况符合,为振动压路机相关参数的设定提供理论依据.

To validate the reliability of a dynamic two degree-of-freedom model of the existing ＂vibratory roller-asphalt pavement＂ system, an asphalt pavement-eccentric block-virtual prototype model of vibratory roller was built using ADAMS soft. The proper pavement stiffness value was determined, displacement, velocity and acceleration response diagram of the roller acquired, and the roller parameter changes corresponding to the changed pavement stiffness value attained. The verification figures agree with the actual working condition, thus providing theoretical grounds for setting relevant parameters of vibratory rollers.
