| Abstract: |
| Based on Differential Quadrature Method (DQM) and multi-resolution analysis theory, the Wavelet Diffential Quadrature Method(WDQM) is proposed in this paper, in which the interpolation basic function is formed by using scaling function. The stability of simply supported Kelvin viscoelastic pipes conveying fluid is investigated by the method. The variation of complex frequencies of the pipe with the internal fluid speed under different parameters are given, and the effects of external fluid speed on vibration behaviors and stability of Kelvin visco-elastic fluid-conveying pipes with different delay time of the visco-elastic material are analyzed. |
