Title Artillery weapons fire intensity factor Simulation of influence
Abstract
The maximum range of ground artillery fire intensity is an important tactical and technical performance indicators artillery weapon system.In order to research factors of artillery firing density effect,The study was based on the Spin-stabilized projectile system. Firstly, the forces and moments acting on rocket were analyzed.a six free degrees rigid model was built.In the model considering the wind, initial disturbance, mass eccentricity, elastic dynamic unbalance factor.based on the model, Write a simulation program to Calculate trajectory equation of a artillery projectile with Matlab,And with the simulation program to study the effect of Weight,wind, initial disturbance, mass eccentricity, elastic dynamic unbalance factor on the intensity of artillery fire. establish a quantitative relationship between the intensity of artillery weapons fire and various factors,Provide feasible to increase the intensity of artillery weapons fire ideas and means.
