结构-音场耦合问题特征值有限元逼近(英文)

摘要

讨论了结构-音场耦合问题特征值有限元逼近,基于估计与外推技术,分析了计算效率,数值结果验证了分析与方法的有效性.%The FEM application to eigenvalue of the structural-acoustic coupled problems is discussed. The computational efficiency issues are analyzed based on the estimations and extrapolation techniques. Numerical results are given and taken as examples to demonstrate the validity of the analysis and the proposed method.
