N2 - In order to predict the high-frequency shock response of plates, a novel hybrid method based on energy finite element method (EFEM) and virtual mode synthesis and simulation (VMSS) is proposed. The EFEM is adopted to calculate the frequency band average of the frequency response function (FRF). Then, the frequency response function is used to solve the virtual mode coefficients by VMSS method. Finally, the high-frequency shock response is calculated by Duhamel integral and the shock response spectrum (SRS) is evaluated. In order to demonstrate the feasibility and advantages of the proposed method, a simply supported plate is utilized for a comparative study. The shock response spectrums of the plate under a triangular pulse load are obtained by using the present method, the finite element method (FEM) and the statistical energy analysis (SEA), respectively. The results indicate that the present method requires much less number of elements than FEM and can be applied to predicted shock response of plates under high-frequency impulsive load.
