摘要
分析了阻尼减振降噪结构模型中几何参数的特性及其对结构损耗因子的影响。对采用非间隔式阻尼层结构和间隔阻尼层结构几何参数进行了研究，最后对大型履带式拖拉机行走系进行了阻尼减振降噪结构的实际应用和性能对比试验分析。
The characteristics of geometrical parameters are analyzed in a model of damping strucures for vibration noise controls, and their effects upon the structural loss factor are studied. Researches on the differences of geometrical parameters between non separate and separate damping structures are made. Finally, practical units are successfully applied to undercarriages of heavy duty crawler type tractors, and the analyses of their experimental properties also are carried out.
