摘要：
The influences of the structural parameters of self-propelled gun on the position and attitude of projectile at muzzle should be reasonably assessed to improve the firing accuracy of self-propelled gun. An integral launch dynamics model of a self-propelled gun is established to solve the problem above. Then an approach of global sensitivity analysis is presented, which is based on the Rosenblatt transformation. In the approach, the first-order and total sensitivity coefficients of an independent variable are estimated with the help of a random continuous independent variable, and the first-order and total sensitivity coefficients of independent variables are estimated with the help of a set of random continuous independent variables. The global sensitivity analysis of a self-propelled gun's structural parameters for position and attitude of projectile at muzzle is conducted lastly based on the proposed model and the suggested approach. The results show that the longitudinal moment of inertia of chassis in the vertical plane is a main factor influencing the position and attitude of projectile at muzzle at the maximum range. © 2021, Editorial Board of Acta Armamentarii.
