摘要
履带销作为履带行走设备中的主要工作部件,其销轴的疲劳寿命对于整机的工作可靠性起着决定作用。通过名义应力法和S-N曲线估算销轴的疲劳寿命,进而估算整机的工作时间,同时结合数学模型对履带销轴的寿命进行分析。
As the main working part of the crawler equipment, the fatigue life of the pin of the track pin plays a decisive role in the reliability of the whole machine. Estimates the fatigue life of the pin by the nominal stress method and S-N curve, and then estimates the working time of the whole machine, and analyzes the life of the track pin with the mathematical model.
