【摘要】 分析我国《起重机设计规范》(征求意见稿)结构疲劳强度计算部分的改动,并以3台大型岸边集装箱起重机为实例,对用各种标准的疲劳强度核算规定(包括应力比法和应力幅法)的计算结果进行比较,发现用这些应力幅法验算的结果普遍严于用应力比法验算的结果.更多还原

【Abstract】 The changes in checking structural fatigue strength of crane design rules(draft for soliciting opinions) are summed up.The calculating results of fatigue strength on 3 quayside container cranes according to several kinds of standards(including stress range method and stress ratio method) are compared.It is found that these stress range methods are generally stricter than stress ratio methods.更多还原
