基于随机游走算法的TMD减振轨道参数优化
Parameter Optimization of TMD Vibration-reducing Track Based on Random Walk Algorithm
摘要
Abstract
The track structure parameters have a significant impact on the vibration reduction performance of the track.In order to select the optimal parameters for the Tuned Mass Damper(TMD)track structure,a vehicle-track dynamic interaction model and a tunnel-ground coupled finite element model were establishes to predict the vibration response of the tunnel wall.Using the random walk method,with the total vibration acceleration of the tunnel wall as the objective function,the width,thickness,stiffness beneath the TMD plate,damping,and the stiffness beneath the track slab were analyzed,and their parameter global optimization was performed within the engineering permissible range to minimize the objective function,so that the optimal track structure parameters were obtained.The results show that when the train speed is 160 km/h and the track slab is supported by rubber mats,the total vibration of the tunnel wall of the TMD vibration-reducing track is reduced by 3.3 dB compared to a conventional floating slab track;when the track slab is supported by rubber springs,the total vibration of the tunnel wall is reduced by 4.1 dB.Moreover,compared with the conventional floating slab track,the TMD vibration-reducing track experiences bifurcation at the natural frequency of the track slab with two peaks formed.After the bifurcation,the peak values decrease,which significantly suppresses the resonance of the track slab in the frequency range around 16 Hz.It is concluded that the optimized TMD vibration-reducing track offers a 3-4 dB vibration reduction compared to the conventional floating slab track and can effectively suppresses the resonance at low frequencies.关键词
