摘要
通过疲劳损伤及疲劳极限两种方法计算弹性旁承体金属骨架的疲劳寿命,通过计算确定弹性旁承体金属骨架可以循环使用1 000万次,因此弹性旁承体金属骨架具有回收价值,可以再循环使用弹性旁承体一个寿命期。
In this paper,fatigue life of elastic side bearing body metal skeleton is calculated by two methods of fatigue damage and fatigue limit.Through calculation,it is determined that the metal skeleton of the elastic side bearing body can be recycled 10 million times.Therefore,the metal skeleton of the elastic side bearing body has the value of recovery and can recycle a life period of the elastic side bearing body.
