摘要在现代战争中,通过改进常规弹药来提高精确度已经占据了战争重要地位,不仅可以有效地打击目标,而且能够降低制造成本。
在了解各国一维弹道修正弹药发展的基础上,提出一种新型一维弹道修正方案,阐述了其系统组成和工作原理,并以某型号的火箭弹为背景,使用Pro/E软件进行三维模型建立,并设计出弹丸总体结构;使用MATLAB软件建立了弹丸的弹道数学模型,仿真计算了该一维弹道修正方案对弹丸弹道的修正能力;同时使用ANSYS软件分析计算了该阻力机构的危险截面的强度是否满足要求。本文的研究为一维弹道修正弹的研制提供了理论依据。61139

Title The structural design of one-dimensional trajectory correction components
Abstract:
In modern battlefield, the trajectory correction projectiles formed by improving conventional ammunition are playing an important role, which not only have the higher attack precision, but also decrease the cost of the projectiles, far less than the missiles.
In understanding on the basis of the one-dimensional trajectory correction ammunition development of all countries, put forward a new type of one dimension trajectory correction plan, expounds its system composition and working principle, and with the background of a certain type of rocket, using Pro/E software to establish 3 d model and general structure of design of projectile; Ballistic mathematical model of the projectile is established using MATLAB software, the simulation calculation by the one-dimensional trajectory correction scheme of the projectile trajectory correction ability; At the same time, the resistance mechanism are calculated by using ANSYS software to analysis the dangerous section of the intensity of whether meet the requirements. In this paper, the research for the one dimensional trajectory correction shell to provide a theoretical basis.
Keywords: trajectory correction, structure design, strength analysis, trajectory model, correction characteristics
