身管与弹丸的熔融磨损模型与研究

针对身管的烧蚀磨损会制约武器的进一步发展的问题，提出一种身管与弹丸的熔融磨损的计算方法。通过分析管与弹丸发生熔融磨损过程，将摩擦学和流体力学相关理论运用到身管与弹丸的高温、高速摩擦作用中，建立了身管与弹丸的熔融磨损模型，推导出了熔融润滑状态下的熔化液熔化速度、熔化液厚度及摩擦系数的计算公式，并以某加农炮为例对所建模型进行理论计算与分析。计算结果表明：该方法较好地符合了现有的摩擦学理论，为深入研究身管武器的烧蚀磨损机理提供了理论基础。

Model and Research of Melting-wear Between Projectile and Gun barrel

Aiming at the problem of erosion and wear of gun barrels will restrict the weapon’s further developments, proposes a method for calculating melting-wear of the projectile and gun barrel. By analyzing the process of the melting-wear, use the tribology and hydromechanics theory, the melting-wear model of the interaction with high temperature and high speed between projectile and gun barrel was established and the related parameters of melting speed and thickness of melted liquid and the friction coefficient were derived. With cannon as an example, the theoretical calculations and analyses were conducted based on the established model. The obtained results were in good agreement with the current tribology theory. The melting-wear model in this paper can provide theoretical references for further studies of the erosion and wear mechanism of gun barrels.
