摘要
本文讨论了枪炮内弹道问题中的枪筒瞬态温度场和动态热应力问题.射击过程中弹头在枪筒内前进时,火药燃烧产生的高温和高压作用在弹头后面的圆筒内壁上.本文给出这种状态下圆筒热弹性问题的控制方程组,讨论了相应的泛函,给出有限元法的计算结果.
The transient temperature distribution and dynamic thermal stress in gun barrel,the one of theproblems of interior ballistics,are studied in this paper.The high blast temperature and pressure apply on the inner surface of the barrel behind projectilemoving in barrel during rapid firings,with this condition the governing equations of the thermoelasticproblem for hollow cylinder are given,corresponding functional is considered and the results calculatedby FEM are given.
