长寿命路面疲劳寿命预测的频域分析方法
Fatigue Life Prediction of Long-Life Pavement Using Frequency-Domain Analysis
摘要
Abstract
This paper analyses a pavement fatigue life prediction method for asphalt and cement concrete pavements. A detailed fre-quency domain analysis of fatigue life was carried out. Using the vehicle-road coupled vibration system model, the random vibration between the vehicle and road caused by road roughness was analyzed. In this paper, it is proposed that the random power spectral den-sity of the vehicle-road coupling vibration is a useful tool to predict the fatigue life of pavements, and corresponding prediction proce-dures are proposed, which are aimed at providing some reference for long-life pavement design and performance evaluation.关键词
