【摘要】 传统的反后坐装置使得火炮质量重，结构复杂，发射时火炮炮架受力大，已经无法适应时代发展需求，这就迫切需要改进传统后坐装置的新技术，来减小火炮发射时炮架的受力，提高火炮的机动性和威力。采用前冲技术应用于火炮反后坐装置就是其中有效的技术之一，同时减轻火炮质量的公认有效措施之一。前冲炮是与传统火炮有着很大的不同，就是在它点火前先给它一动能，用以点火后抵消一部分后坐动能，从而减轻火炮发射时炮架的受力。火炮前冲发原理，是指在炮身后坐过程中，利用一些方法来消除炮身后坐动能，从而减少作用于炮架上的力。炮架受力的减少，意味着结构设计尺寸的减少、重量的减轻，这不仅给炮架的结构设计、加工、安装及使用带来方便，而且还节约了大量贵重金属材料主，更为重要的是，将大提高火炮作战性能。本文对火炮前冲击发原理进行了比较系统的理论分析，并利用前冲原理来设计某122榴弹炮反后坐装置，以达到在保持良好稳定性的情况下，尽可能减小火炮发射的后坐力。因此本文所提出的前冲式反后坐装置，对有效减小炮架受力，提高火炮机动性和威力提供了思考方法。更多还原

【Abstract】 The principle of forward rushing of certain 122mm howitzer, refersto that during thebody of ordnance backlashes, some methods are utilzed to consume the recoiling kineticenergy, which thereby can reduce the force acted on the ordnance’s frame. The reductionmeans the decrease of size, weight and so on, which can not only bring convenience tostructure design, processing, installation and using, but also economize a great deal ofprecious metal materials. Furthermore, the application of this principle makes it possibleto make ordnance light and improve the campaign ability.In FOOB mode, the firing sequence is radically different than that for a conventionalweapon. The gun is captured and preloaded in its out-of-battery position prior to firing.This position compares to a conventional system’s maximum recoil location. Whenunlatched, forward momentum is imparted to the recoiling parts, which will eventually beopposed by the ballistic force imparted by firing a round. The ballistic impulse imparted tothe gun reverses the momentum and returns the recoiling parts to their latched positionready for the next round.This paper puts up a relatively systematic and theoretical analysis on the principle offorward rushing, which may also be called the principle of eliminating kick The paper alsopresents the design and calculating methods making use of the principle.The methods of theoretical analysis and calculating presented here are effective todesign this kind of ordnance They also have important reference value on applicationtechnologies of designing such ordnance in the future更多还原
