In this paper, the probability distribution law of the maximum value of the stochastic pressure is studied in detail. Simultaneous point maximum value method and Monte Carlo statistical simulation method are proposed to determine the maximum value distribution. The application of these methods to the structure and reliability of fuze The influence of the projectile response at design time is analyzed, and the acceleration response random process at some fuze fuze location is taken as an example to analyze and calculate. Practical examples show that the principles and methods presented in this paper can achieve quite satisfactory engineering accuracy requirements.
