查询词典 breech-loading

Guns with the least 'leakage' are best, so a sealed breech (e.g. bolt action) is preferable and can be suppressed to the point that the "click" as the striker or hammer falls is the loudest sound of firing.

渗泄&最小的枪枝效果最好，所以枪膛密封的结构是最宜采用的方式，对这类枪的抑制效果能做到使射击时发出的最响的声音是击针或击锤落下时发出的&嗒声。

The principle and methodology of assembly level finite element modeling and analysis of gun breech mechanism were put forward in this paper.

该文针对火炮炮尾炮闩机构提出了对其进行装配体有限元分析的方法和建模原理。

The main reason causing the breakage of the breech mechanism has been disclosed with analysing the distribution and magnitude of the dynamic stresses in two different situations. This provides useful references for mechanism design.

通过分析机匣在两种不同情况下动态应力的分布，揭示了导致机匣破坏的主要原因，为机构设计提供了有益的参考。

The traditional practice of finite element analysis of gun components was on the basis of single part,it cannot accurately simulate the mechanics behavior of some gun components with multiple parts such as breech mechanism.

火炮构件有限元分析的传统方法是对单件进行建模分析，不能准确地对炮尾炮闩多零件装配体力学行为进行模拟。

A finite element modeling and analysis of the assembly of a breech mechanism in locking condition was carried out with special finite element techniques such as contact element, gap element and spring element.

利用接触元、间隙元和弹簧元特殊单元，对某大口径火炮的炮尾-闩体-曲臂机构进行了闭锁状态下装配体有限元建模和分析。

Combined with the 10th five -year key advanced research project of national defense "Firing technology for rifles with variable-firing-rate and double cyclic systems", the impacting dynamic stresses of this kind of rifles three key elements(breech mechanism, receiver, firing pin) are analysed and studied in this paper.

本文结合&十五&国家重点预研项目一&步枪双循环变射频发射技术研究&，对变射频步枪的三个关重件在撞击条件下的动态应力进行了分析研究。
