Although plate vibration induced by TBL has been widely investigated for long,the works still need to continue for some unsolved issue.A simply supported rectangular elastic plate driven by TBL excitation from wind tunnel test for aircraft is investigated in the paper.In order to simulate the TBL excitation more exactly,three kinds of TBL types including attachment flow,separation and wave oscillation are used for TBL modification. Except that the detailed analysis of plate response induced by different TBL condition is also the key point of investigation.
