| 摘 要： | 本文介绍导气式自动武器在火药气体作用时期内活塞运动诸元的数值解法,据气体动力学原理建立的理论公式,必须采用数值解法才能求解。数值解法中用龙格一库塔法比差分解法更为简便,精度也较高。并编制了一个计算活塞运动诸元?导气装置结构诸元的通用程序,利用它对四种不同的导气式武器进行了计算,结果与实际比较符合。

| Abstract: | This paper introduces a numerical method for cal-culating the piston movement data of gas operated weapons during thetime the powder gas pressure act. The theoretical formulae can onlybe solved by numerical method. The Runge-Kutta method of the nume-rical methods is more simple, more convenient and has higher precisionthan the difference method. A general programme for calculating thepiston movement data and composition data of gas operated device iswritten out. This program has been used to culculate the data of fourdifferent kinds of gas operated weapons. The agreement betweed theresults obtained from calculation and those got from experimental in-vestigations are quite good. |
