Vibration reduction damper and design method
The invention provides a vibration reduction damper and a design method.The vibration reduction damper comprises a shell suitable for being assembled on a steel rail; the damping assembly is installed in the shell and suitable for absorbing vibration energy transmitted by the steel rail, the damping assembly comprises an elastic rubber layer, and a first damping unit of a solid structure and at least one second damping unit of a hollow structure are arranged in the elastic rubber layer at intervals; the second damping unit is filled with particles in a free state, so that the second damping unit and the first damping unit have different inherent frequencies, and the action frequency range of the damping assembly is widened.
本公开提供了一种减振阻尼器及设计方法，其中，减振阻尼器包括外壳，适用于装配在钢轨上；以及阻尼组件，安装在外壳的内部，适用于吸收钢轨传递的振动能量，阻尼组件包括弹性胶层，弹性胶层内间隔设置有具有实心结构的第一阻尼单元和具有空心结构的至少一个第二阻尼单元；其中，第二阻尼单元内部填充有自由状态的颗粒，使第二阻尼单元与第一阻尼单元具有不同的固有频率，以拓宽阻尼组件的作用频率范围。
