摘要/Abstract

摘要： 为了精确地建立磨损内膛有限元模型，提出分片拼接法，建立身管内膛的参数化实体模型；提出节点偏移法，构建磨损程度不同的内膛有限元模型；通过搭建磨损内膛的弹炮耦合模型，并计及磨损内膛体积增大量，采用热固耦合有限元法分析了火炮内弹道膛压和弹丸初速的退化过程。通过对比仿真结果和实验数据，验证了上述建模方法的正确性。该研究不仅对身管的设计和分析具有参考意义，也可以为火炮内弹道的性能退化提供评估方法。

Abstract: In order to accurately build the finite element model of worn gun barrel, a piecewise-connection algorithm is designed to generate parametric 3D solid model of bore, and a node-offset algorithm is proposed to construct the finite element analysis model of bore with different wear degrees. Based on the projectile-barrel interaction model of worn barrel, and taking account of the increment in bore's volume, the interior ballistic process is simulated by the thermo-mechanical coupling finite element method. And the main reason of degradation in muzzle velocity and chamber pressure for a 23 mm gun is also studied. The simulated result matches with the experimental data, which verifies the correctness of the proposed modeling method and meshing strategy. The present study not only has important guiding significance for the design and analysis of gun barrel, but also provides an evaluation method for the performance degradation of interior ballistic process.

Key words: ordnance science and technology, gun bore, 3D solid model, finite element model, projectile-barrel interaction, interior ballistics, wear
