吊杆驳浮式起重机底部加强结构疲劳分析

Fatigue Analysis of Crane Bottom Strengthening Structure for Derrick Barge

本文介绍一种配备浮式起重机的的吊杆驳吊机基座底部加强结构疲劳强度的分析方法;并以某集装箱吊杆驳船为例,通过有限元软件计算分析浮式起重机回转各工况的应力水平及应力幅;针对其使用频率,对比对应的S-N曲线,验证其是否满足要求。

This paper introduces an analysis method of fatigue strength of the crane base bottom strengthening structure of the derrick barge.Taking a container derrick barge as an example,the stress level and stress amplitude of the strengthening structure for different slewing conditions are analyzed by finite element software.According to the its use frequency,the corresponding S-N curve is compared to verify whether it meets the use requirements.
