测试弹性垫板摩擦阻尼性能的方法、装置及测试设备
摘要：
本发明涉及测试弹性垫板摩擦阻尼性能的方法、装置及测试设备，属于轨道结构动力学设计领域。该方法包括：对弹性垫板进行预加载，以消除弹性垫板的马林斯效应；对所述弹性垫板的预设测试点中的每个测试点进行静力加载，获得所述弹性垫板的弹性恢复力与位移的第一曲线；对弹性垫板进行周期性加载，获得弹性垫板的弹性恢复力和摩擦力的合力与位移的第二曲线；根据第一曲线和第二曲线，获得弹性垫板的摩擦力与位移的第三曲线。通过该方法可以获得弹性垫板的摩擦阻尼性能，进而可以根据该摩擦阻尼性能对弹性垫板的减振耗能特性的影响，开发出适用性更强的减振产品。
摘要（英）：

The invention relates to a method and a device for testing the frictional damping property of an elastic base plate and test equipment and belongs to the field of dynamic designs of track structures.The method comprises the following steps: pre-loading the elastic base plate so as to eliminate a Mullins effect of the elastic base plate; performing static force loading on each test point in presettest points of the elastic base plate so as to obtain a first curve of elastic restoring force and displacement of the elastic base plate; performing periodic loading on the elastic base plate so asto obtain a second curve of a resultant force of the elastic restoring force and friction force of the elastic base plate and the displacement of the elastic base plate; and obtaining a third curve ofthe friction force and displacement of the elastic base plate according to the first curve and the second curve. According to the method disclosed by the invention, the frictional damping property ofthe elastic base plate can be obtained, and vibration reduction products with high applicability can be further developed according to the influence of the frictional damping property on the vibration reduction and energy consumption characteristics of the elastic base plate.
