车辆段道砟垫减振特性分析研究

Analysis and Study on Vibration Reduction Characteristics of Ballast Mat in Vehicle Section

以实测数据为依据,分析了道砟垫在车辆段咽喉区的减振效果应用,并对上盖部分进行振动对比,分析了道砟垫对上盖的减振作用,指出在进行上盖开发设计时,对咽喉岔区可采用有砟轨道结合道砟垫的减振方式,减振效果插入损失达8.2dB,可满足咽喉区上盖开发的环境需要。

Based on the real measuring data,the paper analyzes the application of vibration reduction effect of ballast mat in pharynx and larynx area of vehicle section.The paper carries out the vibration comparison on the upper structure(real estate)part,analyzes the effect of ballast mat on the upper structure vibration reduction.The paper points out that the pharynx and larynx area can adopt the vibration reduction mode that track ballast combines the road ballast while carrying out the upper structure development and design.The loss of vibration reduction effect reaches at 8.2dB to meet the environmental requirement of the upper structure development in the pharynx and larynx area.
