Analysis of Vibration Energy Transfer Characteristics of Metro Depot Based on Power Flow
摘要
Abstract
The energy propagation characteristics of subway train-induced vibration in track structure and operation house of the depot were studied.With a depot as the research object,the track-ground-depot simulation calculation model of depot operation house was established.The accuracy of the simulation model was verified by field test data.The finite element power flow method was used to calculate the power flow.Considering the strong vibration isolation performance of material and structure of rail fasteners,the propagation attenuation law of track vibration energy under different fastener stiffness and train speed was analyzed,which may provide a certain reference for the layout planning of the superstructure of the depot.The results show that with the decrease of fastener stiffness,the frequency of the peak value occurrence of the rail power flow reduces,the corresponding peak value of power flow increases,and the vibration energy change of the maintenance column at 63 Hz is the largest.The 3-times reduction of the fastener stiffness leads to a 13.7 dB decrease of the power flow of the maintenance column.The change of fastener stiffness only affects the vibration energy of the structural column within 31.5-150 Hz range,and has the greatest influence on the power flow of the structural column at 63 Hz.The average vibration power flow at the rail,maintenance column and structural column is reduced by 1.23,1.28 and 0.63 dB,respectively,for every 1 km/h reduction of the train speed.关键词
