Abstract: The
nonlinear oscillating boundary element method on the oscillating fluid
mechanics theorem is presented for the flow structure vibration
reliability prediction of turbo machine. The method includes the
nonlinear oscillating mathematics model of the flow induced the
vibration of the structure, the direct solution of the nonlinear
oscillating boundary integral numerical equations and the algorithm of
the fluid structure vibration reliability prediction. The numerical
example for the structure reliability prediction of the turbine blade
shows that the method is fast and effective. The method can be developed
for flow structure stability assessment and the flow induced vibration
analysis of pipe system in chemical process and power engineering.
