边界元特征值分析及 Burton-Miller法探究
BEM eigenvalue analysis and the investigation of the Burton-Miller method
摘要
Abstract
A boundary element eigenvalue analysis method is developed with a contour integral method w hich is used to convert the boundary element nonlinear eigenvalue problems into small generalized eigenvalue problems .Numerical examples are utilized to demonstrate the accuracy of the developed method .Fictitious eigenfrequency phenomena of the conventional boundary integral equation ,its normal derivative formulation and the Burton‐Miller formulation are investigated through exterior acoustic examples .The actual effect of the Burton‐Miller formulation on the fictitious eigenfrequency problems is revealed and the optimal choice of the coupling parameter is confirmed .关键词
