Abstract
Aiming at the problem that the accuracy of interior ballistic parameters was affected by the difficulty in accurately simulating the mass distribution characteristics of airborne missiles in the design of simulated missiles,the distribution law of real missile characteristic parameters was studied by using statistical theory,and the multiple linear regression analysis was carried out.Based on MATLAB software,the distribution law of mass,centroid,polar moment of inertia,equatorial moment of inertia and eccentricity was obtained by K-S test method.Based on the SPSS data processing platform,the linear relationship of the real missile characteristic parameters was obtained by using the least square method and multiple linear regression analysis.The results show that the mass and eccentricity of the projectile without the warhead obeyed the Weibull distribution,and the center of mass and the polar moment of inertia obeyed the normal distribution.The mass,centroid and polar moment of inertia of projectile with warhead obeyed normal distribution,and the equatorial moment of inertia and eccentricity obeyed normal distribution and Weibull distribution.The polar moment of inertia of projectile without warhead was inversely proportional to the square of mass and proportional to the first square of equatorial moment of inertia.The equatorial moment of inertia was inversely proportional to the first and second square of polar moment of inertia.The equatorial moment of inertia of projectile with warhead was inversely proportional to the first power of mass.关键词
