【摘要】 随着计算机技术的发展,系统仿真作为一种先进的计算机技术,已经被广泛应用于国民经济和国防建设的各个领域。同时,为了适应现代战争要求和科学技术的进步,外弹道学在近几十年得到了快速的发展。外弹道系统仿真对新型武器系统的研发有着相当重要的作用。本文对某计转数定距空炸榴弹的外弹道系统进行了仿真研究。文中阐述了系统仿真技术、外弹道学及面向对象技术的基本概念与理论,为课题研究奠定了理论基础和方法框架;根据课题研究目的,利用外弹道学的有关理论,描述了系统的定义,建立了系统的数学模型;根据系统的数学模型,设计了仿真算法;运用面向对象方法和Visual C++编程工具,开发了系统仿真软件;利用所开发的仿真软件,进行仿真试验,并围绕研究目的对试验结果作了分析讨论。通过仿真研究,得到了某计转数定距空炸榴弹的射角、射程、弹丸转动圈数之间的关系模型,为武器系统实战时的弹道解算提供依据。同时,经过分析认为,本武器系统实现有效空炸的射程范围小于520m,同一射角处初速变化时,造成炸高和炸距变化,且炸高变化较小,炸距变化较大,因此有必要在弹道解算时,根据初速变化对装定圈数值进行修正以提高武器系统的打击精度。论文的研究成果对指导某计转数定距空炸榴弹武器系统的研制具有重要的意义。更多还原

【Abstract】 With the development of computer technology, system simulation was applied in domestic business and national defence building as an advanced technology. The same time, to adapt to modern warfare requirements and developing of science and technology, exterior ballistics developed rapidly in recent decades. Exterior trajectory system simulation is very important for developing new weapons.This paper investigated the exterior trajectory system of a rotation number counting shrapnel for air burst in fixed distance by simulation. The following tasks was completed: Basic conception and theory about technology of system-simulation、exterior ballistic and technology of object-oriented were described , theory foundation and method frame is settled;According to the research purpose , take use of the theory about exterior ballistic, described the system define and set up the mathmatic model;On the basis of mathmatic model, the algorithm of simulation was designed;Take use of the method of object-oriented and Visual C++ programming tool, the system simulation software was exploited; Use the system simulation software, simulation test and test results analyzing center on the research purpose was completed.Model relationship of angle of fire、range and rotation number of shell was obtained which could be the reference of trajectory calculation of weapon system in war time. Meanwhile, be supposed through the analyzing is, the available range for air burst of this weapon system is less than 520 meters, when fire velocity changed in one fire angle, the burst height and range change linked, less in the burst height and more in the range, so, in order to enhance the fire accuracy, it’s necessary to correct the rotation number in exterior trajectory calculation. Achievements in research with great significance in instructing the developing of rotation number counting shrapnel for air burst in a fixed distance.更多还原
