| 摘 要： | 以一种适合港口施工作业的新型自行式施工平台为研究对象,介绍了该型平台特点与工作流程。根据其工作行走状态及载荷特点,使用有限元方法分析多工况下平台的结构屈服强度,并根据规范进行平台和桩腿结构屈曲评估。该平台由上下两层平台组合而成,针对此平台上下层接触的特点,探讨了不同类型MPC,ABAQUS接触分析的结构强度计算结果。研究对自行式海洋平台设计具有借鉴意义,并对平台结构强度计算研究提供了一定参考。

| Abstract: | This paper introduces an innovative self moving platform which is suitable for offshore practical construction. The characteristics and working process of this platform are also described in detail. According to its working and moving characteristics and load conditions, the structure of this platform is calculated using FEM in order to check the yield strength. The buckling strength assessment of the platform and legs is conducted according to the rules for the classification. Because the platform is composed of upper platform and lower platform, two MPC methods and ABAQUS calculation are compared to simulate the contact between them so as to calculate more precisely. As a result, the research will be helpful to the design of self moving platform and provide reference on the structure calculation of platform. |
