浮置板轨道竖向振动能量传递分析

Analysis of Vertical Vibration Energy Transmission of the Floating Slab Track Structure

从减振降噪的角度讲,应尽量减少输入到结构的振动能量,本文根据浮置板轨道结构的特点,从能量角度出发,根据振动分析中的功率流理论,分析推导了浮置板轨道传递到基础的振动功率流,并就该轨道结构影响振动能量传递特性的参数进行了分析计算。

The effect of isolation of the floating slab track can not be judged only by the force transmitted to the foundation. Based on the characteristics of the floating slab track and the theory of power flow of vibration, from the energy point of view, the power flow spectrum, transmitted from the track structure to the foundation, is analyzed and calculated, and the track structure parameters that affect vibration energy transmittion are analyzed.
