Abstract：Here,a new mathematical model of accelerated vibration fatigue testing was established under super-Gaussian random vibration excitation using theoretical analysis,and detailed solving methods were presented for unknown parameters in the model.The model was verified with the actual tests.It was shown that the model can be effectively used for the practical quantitative design of accelerated vibration fatigue tests,it can be applied to assess the fatigue life and reliability of engineering structures under random vibration environment.
