某型舰炮炮箱进弹口弹链尾钩运动支撑面壁厚优化

Optimization of the Receiver Thickness of Ammunition Chaining Rail for Chain-tail of A Navy Gun's Box

舰炮实际生产和应用中,常常遇到因部件变形引起的改变运动性能的情况,如某型舰炮炮箱进弹口弹链尾钩运动支撑面因壁厚不足产生变形,将会影响供弹通畅性,甚至影响弹链的整个运动过程,导致卡弹。针对此,通过对该处壁厚尺寸链和受力分析计算及受力有限元分析,分析影响变形的主要原因是壁厚累积公差较大,当壁厚处于下限时,支撑面容易变形。因此,制定出最小壁厚标准,提出控制该处壁厚的方案,从而为后续生产、优化提供理论依据。且此种分析思路、方法为机械装备在设计、生产改进中遇到类似问题提供方法支撑。

In the actual production and application of the navy gun, the performance of the changes caused by component deformation is often encountered. The chain-tail operating bearing surface in some kind of Naval gun＇ s receiver will be deformed for it＇ s thickness, then, decreasing the flexibility of ammunition chaining. It will affect the moving of bullet and even affect the whole process of the elastic chain. This article analyze the dimension chain and force of the bearing surface and Finite element analysis, found the tolerance of bearing surface＇ s thickness is so wide. When the bearing surface thickness is at the minimum, it will be deformed when supplying ammunitions. For this question, we try to establish the thinnest thickness for the bearing surface of the receiver, to supply the theoretical basis for manu- facturing and optimizing. And the whole analysis thought provide a method support in design, production improvement encounters similar oroblems.
