Abstract

To study the temperature distribution characteristics of small artillery barrel under different shoot conditions, this article first establishes the propellant gas temperature equations during the interior ballistic period and the aftereffect period, based on which the initial conditions of heat transfer is determined; then analyzes the heat transfer coefficient of bore-surface during the interior ballistic period, based on which heat transfer boundary is clarified; and then establishes the heat transfer model of artillery barrel based on the theory of heat transfer, solve the model on basis of the finite difference method; finally analyzes the temperature field distribution and variation law under the single and repeating firing conditions, taking the 30mm barrel of chrome plating as an example and draw the conclusion that the temperature gradient near the chromium layer is not notable, which laid the foundation for the research on the life of small caliber barrel next.
