桁架桩腿自升式平台齿条相位差分析研究

Haiyang gongcheng zhuangbei yu jishu
在就位过程中，桁架桩腿自升式平台会产生齿条相位差，在桩腿与平台主船体接触位置产生极大的附加弯矩，导致平台主体下导向位置的桩腿撑管发生屈曲失效。本文以某平台为研究对象，采用ANSYS软件建立平台三维时域有限元模型，并通过生死单元技术实现自升式平台升船过程实时模拟与RPD值预测；根据RPD值的变化情况将升船过程划分为4个主要阶段。在此基础上，对3种风速工况下平台RPD变化特性进行分析，从而判断升船阶段风速对RPD的影响。依据掌握的RPD与桩腿应力的变化规律及许用RPD值，提出一套RPD控制方法 ...
