基于DFR法的工程结构振动疲劳寿命评定
Vibration Fatigue Life Prediction of Engineering Structures Based on DFR Method
摘要
Abstract
An equipment structure with foundry defects was studied herein to acquire the fatigue life based on the DFR method. The data employed in the method were obtained from a series of tests, which were basic mechanical properties, fatigue/crack propagation performance, mode/dynamic response performance,load spectrum of critical site,etc. It is proved that this method provides a reasonable and feasible approach to assess fatigue life of engineering structure under the broad band random vibration environment.关键词
