基于组件的弹射内弹道建模技术

摘要

Mathematical model of its interior ballistics was built according to the ejector’s concrete characteristics and the classical interior ballistic hypothesis.In addition,the writer also partitioned the whole system into several standard components,and built the simulating models of every standard component.Finally a integrate simulation model of ejector system was set up in the Matlab /SimuLink platform.Also the writer did some example simulations of certain ejector system,and the simulation results fit to experiment data very well.%根据弹射器的结构特点以及经典零维内弹道假设，建立了内弹道仿真的数学模型，同时按弹射器的功能特性人为将全系统割分多个标准组件模块，并分别对各组件模块的物理特性构建了独立的分析仿真模型；最后在 Mat-lab ／SimuLink 平台上搭建了基于标准组件的弹射系统集成仿真模型，并对某系统进行了仿真计算，计算结果与试验结果基本相符。
