摘要
基于修正M iner疲劳损伤累积理论,采用在线修正的名义应力估算疲劳寿命的方法,设计了一套大型起重机在线寿命预测系统。通过数据的实时测量对剩余寿命进行修正,更好地结合实际,提供了一种准确、实用的预测起重机安全剩余寿命的新手段。
An on-line residual life correction system for large crane is developed based on modified Miner＇s rule and on-line correction nominal stress method for estimating fatigue life. The system completes the correction of the residual life through real-time measuring related crane data, offering an accurate and practical method for engineering designer to calculate crane＇s fatigue life.
