    摘要:

    针对应变传感器无法覆盖所有结构关键位置的现状,提出了一种基于结构多尺度模拟的应变传感器优化布置方法。首先利用管单元和梁单元建立导管架平台宏观有限元模型,并基于静力分析确定结构的关键区域;其次建立关键区域的三维实体有限元模型,采用多点约束方法进行梁单元和实体单元的耦合,完成结构多尺度建模;最后通过对多尺度模型的力学分析,可以确定应变传感器在关键区域的具体布置位置。以南海陆丰13-1导管架平台为对象,基于所提方法确定了应变传感器的安装位置,从而为海洋平台应变监测传感器的布置方案提供了科学的参考。

    Abstract:

    Aiming at the current situation that strain sensors cannot cover all key positions of the structure, a method for optimal placement of strain sensors based on multi-scale simulation of structures is proposed. Firstly, the pipe element and beam element are used to establish the macroscopic finite element model of the jacket platform, and the key area of ??the structure is determined based on static analysis; secondly, the three-dimensional solid finite element model of the key area is established, and the beam element and the solid element are determined by the multi-point constraint method. Coupled to complete the multi-scale modeling of the structure; finally, through the mechanical analysis of the multi-scale model, the specific placement of the strain sensor in the key area can be determined. Taking the Nanhai Lufeng 13-1 jacket platform as the object, the installation position of the strain sensor is determined based on the proposed method, which provides a scientific reference for the layout of the strain monitoring sensor of the offshore platform.
