Matlab埋头弹药设计及内弹道特性数值研究
查阅国内外关于埋头弹药技术的文献资料，根据埋头弹的设计要求，设计分析了40毫米埋头弹装药结构，采用两次点火及程序燃烧概念，结合经典内弹道理论，建立了40mm埋头弹内弹道理论模型。32746
在建立理论模型的基础上，应用Matlab语言编制了计算软件，对40毫米埋头弹药的一次点火过程、二次点火过程进行了数值模拟，且二次点火过程的仿真结果与实验数据吻合较好。最后，对40毫米埋头弹药的装药量、启动压力、身管长度、药室容积及弹重等装填参数变化时对内弹道性能的影响进行了预测分析。

Title Ammunition Design And Numerical Simulation of Interior Ballistic Characteristics of CTA
Abstract
The cased telescoped ammunition (CTA) technology is a kind of charging technology. in this background, The main research works are as following:
Based on analyzing and collecting a large number of technical literatures about CTA gun both abroad and domestic, according to the characteristics of CTA, The 40 mm CTA charging structure is designed. Apply on twice ignition and program combustion concept and the characteristics of the launch process of CTA gun ,An ignition model of 40mm CTA gun is established.
Based on the ignition model, the simulation tests of once and twice ignitions of CTA gun are carried out. And then numerical simulation of Interior ballistic process of 40mm CTA gun is carried out. Characters of bore pressure, speed varied with time is gutted. The calculated values of the twice ignition are in good agreement with the experimental ones. The software of numerical simulation is developed by using Mat lab language. At last, the influences of different parameters as of charging weight, starting pressure, Chamber volume ，Barrel length and heavy bomb on the interior ballistic performance are studied.
