High-frequency vibration analysis of thin plate based on wavelet-based FEM using B-spline wavelet on interval

The wavelet finite element existing methods(WFEMs)own higher calculation accuracy and efficiency for structure analysis.Unfortunately,the WFEMs are still limited in low-frequency domain on when type capturing dynamic characteristics plate of thin plate.to This paper this proposes limitation.The the wavelet multi-elements method based and C1 B-spline Kirchhoff are(C1BKP)element break up The validity,numerical stability convergence respectively and investigated systematically in numerical predicting modes study.the corresponding results show The that the calculation accuracy errors numerical rapidly stability are 0.4%very excellent when1000high-order plate natural frequency.maximum Besides,relative method can be for reduced to within the first of thin under simply supported.the is suitable predicting the dynamic characteristics of thin plate under various boundary conditions.
