Numerical Simulation of Vibration Characteristic for S-Shaped Inlet

Vibration characteristics of a s-shaped inlet is numerically simulated by finite element analysis technology, and the first ten order modal vibration modes and natural frequencies are extracted. The study shows that the overall performance of modal vibration mode for the s-shaped inlet is the same direction movement of low order modes. It also shows the local movement of middle order modes and multiple local movements of high order modes, and specific forms of movement for the first ten order modal vibration modes are analyzed emphatically.
