基于功率谱密度信号的疲劳寿命估计

A Frequency Domain Approach for Fatigue Life Estimation

简单回顾当前存在的从功率谱密度信号计算疲劳寿命的方法，并将说明Ｄｉｒｌｉｋ方法能给出与传统时域疲劳计算方法最为接近的结果。

This paper will review the available methods for performing fatigue analysis from power spectral density(PSD) and shows that the Dirlik method gives the best comparable results with the traditional time domain approaches.
