摘　　要：针对传统刚性支重轮减振效果较差的现状,将减振性能良好的间隔阻尼层结构(管状)引入支重轮,以提高支重轮结构的损耗因子,改良其减振性能。通过建立支重轮减振模型,推导出其幅频特性函数,结合实际工作状况和支重轮的结构设计出实体模型。以某型号推土机为研究对象,利用Matlab软件编写仿真程序,并将推土机的各项参数带入,仿真结果表明,经过改良的支重轮可对履带式工程车辆的振动进行有效的缓冲,并能避免整机在低频工作状态下发生共振。Aiming at the present situation of poor vibration damping effect of traditional rigid track rollers, a spaced damping layers structure (tube-shaped) with satisfactory vibration damping is adopted on track rollers to increase the loss factor of the roller structure and improve its vibration damping property. Its amplitude-frequency property function is derived through the establishment of the roller vibration damping model and a solid model is designed according to practical work conditions and the roller structure. Taking a bulldozer as research objective, simulation program is complied with Matlab software and every parameter of the dozer is input. The simulation result shows that the improved rollers can effectively impede the vibration of crawler type construction vehicles and avoid the resonance of basic machine under low frequency work conditions.
