Self-Destruction Time Distribution of Fuze Based on Functional Analysis

doi:10.12382/bgxb.2021.0838

Abstract

Abstract:

To deal with the problem that the fuze’s self-destruction time test cannot reflect the self-destruction time distribution when the sample size is small, the initial velocity, self-destruction rotating velocity and time relationship are analyzed. The functional analysis method is used to establish the relationship between the initial velocity and the self-destruction rotating velocity of the ballistic model. The Euler-Lagrange equation is employed to solve the parameters related to the normal distribution of the initial velocity and the self-destruction rotating velocity, and thus obtain the time distribution. The simulation results show that the proposed method can determine the relationship between initial velocity and self-destruction rotating velocity, and verify the effectiveness of the method through hypothesis testing. The joint distribution of initial velocity and self-destruction rotating velocity is used to solve the self-destruction time distribution, so as to obtain the satisfaction of tactical technical indicators. This study provides a more effective method for the performance appraisal test of the firing range, and serves as a theoretical support in terms of self-destruction time for the safety of military training.

Key words: self-destruction time, functional analysis, self-destruction rotating velocity, safety
