摘要
针对TB/T2360,ISO2631和UIC513三种常用的平稳性指标评价方法进行了对比,从加权函数对比标准之间的差异。通过实测加速度数据的频谱构成,认为横向加权函数衰减基本一致,TB/T2360垂向加权函数衰减最大,UIC513的标准评价最为严格。
The author analyzes three commonly used evaluation methods for stability index,TB/T2360,ISO2631 and UIC513,and the difference between the standards is compared from the weight function.According to the spectrum composition and relative sensitivity of the measured acceleration data,the attenuation of the lateral weighting function is basically the same,the attenuation of the vertical weighting function of TB/T2360 is the largest,and the standard evaluation of UIC513 is the most stringent.
