Abstract:The finite element method (FEM) is used to analyze the vibration response of underwater shell structures, and the boundary element method (BEM) is used to analyze structural vibration acoustically. By combining FEM and BEM, the coupled FEM-BEM method is used for the acoustic-vibration strong coupling analysis of underwater thin shell structures. In order to overcome the problems of discontinuity and low precision in the traditional Lagrangian approximate geometric model and physical field interpolation calculation, the Loop subdivision surface isogeometric method is used to construct the geometric model, and the same spline function is used to perform the high-order interpolation calculation of the physical field, so as to realize the integrated CAD/CAE analysis of the underwater acoustic-vibration strong coupling system. Stochastic analysis is devoted to studying the output uncertainty caused by the input uncertainty of the system. Monte Carlo simulation(MCs) is considered to be a universal tool for solving complex and multi-dimensional uncertain problems because of its simplicity and directness. However, the huge computational cost reduces its applicability. Using proper orthogonal decomposition (POD) and radial basis function (RBF) can reduce computational cost, improve computational efficiency, and realize fast stochastic analysis based on Monte Carlo simulation (MCs). Considering the influence of the uncertainty of the structural material property parameters and the structural shape parameters on the calculation results, Monte Carlo simulation is used to analyze the statistical characteristics of the structural acoustic response under random variables. Finally, several practical problems are used to verify the correctness and effectiveness of this algorithm.
