Research On Dynamic Simulation And Visualization Technology Of Parachute Ammunition

Application of parachute technology in military field is very extensive,mainly used for weapons bomb assault weapons and service deceleration,ensure the accuracy of the trajectory,and increase the endurance distance of draw back,increasing the angle into ground or water,to ensure the safety of recovery system for airdrop,scheduled to reach operational effectiveness.This paper studies the model of parachute bomb parachute ammunition ballistic simulation and visualization,the key research content in motion trajectory is the motion attitude of projectile in outer ballistic part,build a visual simulation system,visualization complete trajectory simulation.First of all,the establishment of dynamic model of the various stages of exercise,parachute ammunition in each stage of the study on the stress state and the motion analysis,the motion equation of each flight stage,and the movement process analysis.Secondly,using Matlab/Simulink engineering calculation software is analyzed,get the trajectory parameters of flying projectile and ballistic curve accurately,the modeling and Simulation of trajectory using Simulink module,construct the virtual reality simulation model.Finally,the 3D simulation model of Simulink and Flightgear technology to build missile in different stages and the virtual reality environment based on the realization of the virtual scene interactive data transfer,complete the establishment of exterior ballistic virtual reality simulation model,visualization of projectile trajectory motion.As a small part of the subject of research in the field of parachute weapons.Based on MATLAB software,virtual reality simulation modeling and visualization based on the parachute weapons ballistic movement,in the design of this kind of parachute weaponsystem,can reduce the required amount of experimental time and energy,through the simulation and evaluation of feasibility and disadvantages,can quickly find the error details,and achieve the purpose of optimization by adjusting and modify the parameters of performance but also can be used to analyze and study the existing similar parachute weapons.
