基于流场数值模拟的远程弹尾翼稳定装置设计
|
摘要
本文分析了国内外膛口流场理论的发展现状和趋势,介绍了膛口流场数值模拟方法和膛口流场的基本特性。通过建立的7.62mm步枪膛口流场模型,并采用非结构动网格技术,在模型中加入了湍流模型,得到了与实验照片大致吻合的计算结果,清楚地展示了膛口流场的形成过程。此外,对某大口径火炮含动边界的膛口流场进行了计算,为尾翼的张开运动分析提供了依据。
分析了当前国内外典型超口径尾翼稳定装置的结构和特点,在结构分析的基础上借助后效期的二维膛口流场理论提出了后效开翼的新途径,设计出了一种新型适合远程弹丸的尾翼稳定装置结构,同时对该稳定装置进行了结构分析、强度计算、气动力和稳定性的计算;并且利用二维流场理论分析了尾翼的张开运动,结果证明了该尾翼结构设计方案是可行的。
最后对远程尾翼弹丸外弹道流场进行了数值模拟,结果表明弹丸在飞行的过程中攻角和马赫数对流场的影响,与理论相吻合,对炮弹、特别是尾翼弹的外弹道数值计算方法作了探索性的工作,为炮弹以及尾翼稳定装置的设计提供了依据。
This thesis analyze the current status and tendency of the muzzle of gun flow-field theory both here and abroad.the numerical simulation method and fundamental characteristics of muzzle of gun flow field the fundamental characteristics are introduced.by modelling muzzle of gun flow field of 7.62mm rifle,use non-structure moving mesh technique,and put the turbulence in the model.the result which are approximately consistent with the experiment photos,show clearly establishment of muzzle of gun flow field.besides,the muzzle of gun flow field which contains moving boundary on certain medium caliber artillery is calculated,and the foundation for the unfold motion analysis of the fin is gotten.
By analyzing the features and characters of various kinds of super-caliber stabilized assembly of fin-stabilized projectile domestic and abroad, On the basis of the structural analysis make use of the gas ejection period two-dimension muzzle of gun muzzle of gun flow-field theory to produce the new way of gas ejection period unfolding fin.A kind of new type fin stabilization structure which fits the long-distance projectiles are designed. The structure of the stabilizer is analysed ,and the strength,aerodynamic force and stability of the stabilizer are calculated. By using two dimensional flow field theory to analyze unfold movement of the fin,the results prove the fin construction design scheme is feasible.
In conclusion,the numerical simulation of exterior trajectory flow field on long-distance fin-stability projectile is taken. the results proved that the influence of the angle of attack and Mach number on flow field when the projectile is flying,is consistent with the theory.The exploring work for exterior trajectory numerical implementation of projectile, especially for fin-stability projectile are done,offerring the reference to projectile as well as fin-stability device’s design.
