摘要
基于压路机对土基或路面面层振动碾压受力机理,在土壤和振荡压路机相互作用的基础上,建立振荡轮—土壤的动力学模型.通过Matlab/Simulink仿真,分析振荡频率、介质阻尼系数、刚度系数对振幅的影响.仿真结果表明:振荡压路机的振幅随着振荡频率、介质阻尼系数、刚度系数的增大而减小,介质阻尼是影响较大的因素.研究结果对工程中压路机的工况改进和工作参数合理选择具有实际意义.
Based on the vibration roiling force mechanism of the roller to soil base or road surface and the simplified soil oscillatory roller＇ s interaction, the dynamics model of oscillating wheel --soil is established. Through the simulation based on Matlab/Simulink, the influence of the oscillation frequency, medium damping coefficient and stiffness coefficient to amplitude is studied. The simulation results show that the amplitude of oscillatory roller decreases with increasing of oscillation frequency, medium damping and stiffness coefficient, in which medium damping is the largest factor. The result of simulation has practical significance for improving work conditions and rational choice of operating parameters.
