摘要

针对传统基于逆有限元法(inverse Finite Element Method,iFEM)的损伤监测方法难以实现损伤的定量化评估的问题,本文提出一种融合iFEM与贝叶斯统计框架的板壳结构概率化损伤监测方法。方法利用iFEM的应变外推能力,在不同损伤假设下重构损伤邻域的外推应变场,通过构建外推应变与实测应变的似然函数,实现对损伤参数的后验概率评估,从而实现无需依赖健康基准的贝叶斯损伤监测。研究对矩形板和梯形加筋板分别进行仿真建模分析,验证了采用iFEM在位移与应变重构时的平均误差均低于1.0%,并且得出贝叶斯损伤监测方法在识别损伤时的误差小于7.8%。进一步基于不同尺寸损伤的邻域应变变化趋势,研究了网格划分对该方法准确度的影响,仿真结果表明损伤半径和刚度折减系数均会影响损伤监测准确度。研究搭建梯形加筋板的实验平台,验证了该方法在实际工况下的损伤定量化有效性,监测误差小于6.5%,实现了损伤区域的识别、定位与概率化评估。本文所提方法为板壳结构健康监测提供了一种兼具高效性、准确性与工程适用性的损伤评估新途径。

Abstract

To address the challenge that traditional damage monitoring methods based on the inverse Finite Element Method (iFEM) are difficult to achieving quantitative assessment, this paper proposes a probabilistic damage monitoring method for plate structures that combines iFEM with a Bayesian framework. This method uses the strain extrapolation capability of iFEM to reconstruct the extrapolated strain field near the damage under different damage hypotheses. By constructing a likelihood function between the extrapolated and measured strains, it achieves a posterior probability of the damage parameters, thereby achieving Bayesian damage monitoring without a healthy baseline. Simulation analyses were performed on rectangular plates and trapezoidal stiffened plates. The results show that the average errors of displacement and strain reconstruction using iFEM are below 1.0%, and the damage monitoring error is below 7.8%. The simulation results indicate that both the damage radius and the stiffness reduction factor influence the accuracy of damage monitoring.Furthermore, based on the variation of the strain field near damages of different sizes, the influence of mesh discretization on the accuracy of the method was investigated. A test platform for a trapezoidal stiffened plate was built to verify the effectiveness of the method under practical working. The damage monitoring error below 6.5%, achieving identification, localization, and probabilistic assessment of the damage.
