international roughness index

基本解釋

Then the International Roughness Index used widely in road roughness measuring is explained, Several typical road roughness measuring devices are analyzed…
然后分析比較了目前幾種典型的平整度測(cè)量?jī)x，最后討論了目前平整度測(cè)量方法存在的問題、解決方法及發(fā)展方向。
The correlation between the standard classified road power spectral density(PSD) and international roughness index(IRI) was discussed by using regressive analysis.
通過回歸分析的方法對(duì)標(biāo)準(zhǔn)分級(jí)道路功率譜密度與相應(yīng)國(guó)際平整度指數(shù)之間的關(guān)系進(jìn)行了研究。
This text will draw on the international roughness index to deduce the minimum hortative wavelength, so as to reduce the error during the model conversation and numerical calculation of roughness.
本文將從國(guó)際平整度測(cè)量方法上推知路面激勵(lì)的最小波長(zhǎng)，以減少平整度模型轉(zhuǎn)化和數(shù)值計(jì)算中的誤差。
