摘要
通过对活动钢支座的有限元分析 ,建立支座的三维有限元模型 ,按照活动支座实际的动荷载按应力寿命准则计算屈服强度、Goodman以及Geber失效因子。计算结果表明 ,活动支座的疲劳寿命足够 ,其疲劳强度满足设计要求。
By analysing steel pedestal with fatigue and durability analysis, the Yield Strength factor, Goodman factor, Geber Factor and accumulate damage factor are obtained according to stress life criteria. The results show that fatigue life of the pedestal is enough and fatigue strength can meet with the requirement of design.
