建立列车自动门振动谱时的幅值修正系数

摘要

for the doors, a series of measures should be taken, including revising the amplitude of quasi-vibration spectra, according m the principle of energy conservation. A revised coefficient for lhe amplitude is thus established. And a vibration spectrum is establi,~hed for the vibration time serial detected in a type of train automatic door. The result proves that this method is [easible.%列车自动门振动谱是实施列车自动门振动可靠性实验的基本条件．为了保障所构建的列车自动门振动谱的效果，需要采取一系列措施，其中包括基于能量守恒原则修正准振动谱的幅值，为此建立了幅值修正系数．对检测获得的某型列车自动门振动时间历程构建振动谱，结果表明本文的方法可行．
