摘　　要：针对传统刚性支重轮减振效果较差的现状,采用一种间隔阻尼层式结构,对支重轮减振性能进行改进。以某型号履带式拖拉机为应用实例,建立其整机缓冲模型及单个支重轮的缓冲模型,导出支重轮幅频特性响应函数。使用Matlab分别对传统的及改进后的支重轮进行仿真对比分析,结果表明新型支重轮可有效地缓冲该拖拉机所受的振动。用ANSYS软件对新型支重轮进行强度分析,表明其强度能满足拖拉机各工况的使用要求。Based on the current situation of poor vibration damping performance of traditional bogie wheel, a kind of spaced-damping layer structure was applied to the bogie wheel to improve its vibration damping performance. A crawler tractor was taken as an application example, the vibration damping models for the whole vehicle and single bogie wheel were established, and the amplitude-frequency characteristic response functions of bogie wheels were deduced. With the performance simulation and comparative analysis between the traditional and improved bogie wheels performed by Matlab, the results show that the vibration suffered by the crawler tractor can be buffered effectively by the new bogie wheels. With strength analysis of the improved bogie wheels carried out by ANSYS, the results show their strength can meet the operating requirements under the different working conditions of the crawler tractor.
