Impact Identification Method of Thin-Plate Structure for Subsea Protection Based on Energy Barycentre Positioning

为弥补传统能量重心定位方法的不足,综合考虑薄板结构上孔的非对称分布,创造性地提出一种基于加权能量重心定位的撞击识别方法。通过有限元模拟验证该方法的有效性和准确性,结果表明,该方法能快速而准确地对非对称、非连续薄板结构的撞击位置和撞击应力进行识别判定。研究成果可为结构撞击识别方法的改进优化提供理论支持,为工程中复杂结构的撞击监测和识别提供技术支撑。

An impact identification method based on weighted energy barycenter positioning is creatively proposed with the comprehensive consideration of the asymmetric distribution of holes on the thin-plate structure,to bridge the lack of the conventional energy barycenter positioning.This method can identify and determine the impact position and stress on an asymmetric and discontinuous thin-plate structure rapidly and accurately,and its effectiveness and accuracy are verified by the finite element simulation.The results provide theoretical support for the improvement and optimization of the structure impact identification method,and offer a technical foothold to the impact monitoring and identification of complex structures in practical engineering.
