摘要

建立了轨道车辆“惯容器-弹簧-阻尼”（Inerter Spring Damper,ISD）悬挂结构垂向振动的动力学模型，采用强迫振动理论进行了振动响应特性以及隔振性能分析。研究发现：ISD结构的振幅、振幅放大因子、速度放大因子和加速度放大因子相对质量比存在极小值点，此最优质量比是频率比和阻尼比的函数；阻尼比和质量比建议取值范围为ξ<0.2及0.1<μ<0.3，此时隔振性能可得到最大程度提升；质量比越大，相位差越小。推导了临界频率比、共振点频率比与质量比的关系，质量比越大，临界频率比和共振点频率比越小，共振点处的振幅放大因子以及共振区宽度也明显减小。该结果对轨道车辆ISD悬挂结构的减隔振性能分析和轻量化研究提供了一种新的思路，并对ISD结构设计中关键参数的选取提供了参考。

Abstract

In order to study effects of inerter on vibration response and vibration isolation performance of a track vehicle inerter-spring-damper (ISD) suspension structure, its vertical dynamic model was established.The forced vibration theory was used to analyse the system’s vibration response characteristics and vibration isolation performance.The results showed that there are minimum value points on curves of amplitude, amplitude amplification factor, speed one and acceleration one of ISD structure versus its mass ratio, and these optimal mass ratios are functions of frequency ratio and damping one; the suggested ranges of damping ratio and mass one are ξ<0.2 and 0.1<μ<0.3, within these ranges, the system’s vibration isolation performance can be lifted to the maximum extent; the larger the mass ratio, the smaller the phase difference; relations of critical frequency ratio and resonance point frequency ratio versus mass ratio are derived, the larger the mass ratio, the smaller the critical frequency ratio and resonance point one, and amplitude amplification ratio at resonance point and width of resonance region obviously decrease; the study results provide a new way for track vehicle ISD suspension structure’s vibration isolation performance analysis and lightweight study, and a reference for choosing key parameters in ISD structure design.
