Aimed at the correlation between the impact loads and planing forces of the tail on supercavitating torpedo structure, the pseudo excitation had been constructed about every eigenpair of power spectral density matrix.By using Newmark method with pseudo excitation perturbation method, the computing equation of dynamic reliability are educed from the first excursion probability mechanism. Finally, the method of this paper wasproved feasible comparing with the Monte Carlo method by an example.
