高炮发射动力学仿真技术研究

本文以概要方式介绍了高炮发射全过程的动力学仿真技术，论述了以计算机数学仿真技术为手段，通过建立以振动理论为基础的高炮的空间动力学模型，用内弹道理论和自动机理论分析得到高炮射击时的载荷，计算火炮模型在射击载荷下的动态响应，然后以炮口振动确定弹丸的初始扰动，再以外弹道理论预测射击精度，通过计算机仿真高炮从点燃底火，经弹丸在膛内运动，自动机运动，火炮振动到弹丸飞离泡口，到撞击预定目标的发射全过程，分析影响高炮射击精度的主要因素，为高炮设计研究人员在计算机上分析高炮的主要性能，确定或修改设计方案，以及为高炮总体方案设计，结构优化设计提供技术基础和工具。

A STUDY ON THE DYNAMIC SIMULATION OF ANTI-AIRCRAFT GUNS ON FIRE

In this paper, digital simulation is introduced in solving the shooting accuracy of the anti aircraft gun system Using interior ballistics theory and auto mechanic analysis, the force acting on the gun system is solved Then, by establishing and analyzing the finite element and/or multi body model of the anti aircraft gun system acted on by the shooting force, the system dynamic characteristics of the gun system and the muzzle vibration while projectiles escape from the gun tube are solved Finally, applying theory of external ballistics, the shooting accuracy of the gun is solved By a systematic simulation of the whole shooting process for the system, factors affecting the shooting accuracy can be found, and the method and results can be used to improve the design and analysis of anti aircraft gun systems
