摘要在现代高技术战争的条件下，为了满足作战需求，各国研究人员都在提高弹丸初速方面投入大量精力。其中，随行装药作为一种新型装药技术，给弹丸提速带来了契机。本文基于经典内弹道理论，结合随行装药的特点，构建随行装药的内弹道零文模型，并选用 VＢ６.０软件编制计算程序，使用四阶龙格-库塔法进行数值计算，对３０ｍｍ固体随行装药内弹道过程进行了数值模拟，由此获得的Ｐ－ｔ曲线，与实验结果吻合良好。在此基础上，讨论了点火延迟时间、随行装药量及其燃速等参数的变化对内弹道性能的影响，计算结果为固体随行装药的设计提供了参考。

Title Design of the interior ballistics and Numerical
Simulation for 30mm solid traveling charge
Abstract
In the modern high technology war conditions, in order to meet operational requirements, researchers in worldwide pour a lot of time and energy in improving muzzle velocity.Among them, the traveling charge as a new way to accelerate the projectile brings opportunity. Based on the classic interior ballistics theory,with the characteristics of traveling charge, this paper constructed a zero dimensional interior ballistic model for solid traveling charge, while the method for numerical calculation was the fourth-order Runge-Kutta, calculating program compelled by VB6.0. And the interior ballistics process of solid traveling charge was simulated on 30mm ballistic gun and obtained P-t curve,which agrees with the experimental results well. By this, the paper discussed the effects caused by change of ignition delay time, the amount of traveling charge mass, traveling charge burning rate and other parameters on the ballistic process.And the calculation results of the study of solid traveling charge provides a reference for solid traveling charge design.
