摘要: 分别用延迟温度报警法和实时温度报警法计算了厚壁身管火炮的报警温度,并对这两种方法进行了比较。分析了环境温度、射击模式对报警温度数值确定的影响。计算结果表明,采用外壁温度作为报警判据,在不同模式之间存在着很大的误差,为确保某一工况下的安全射击,势必限制火炮其它工况下正常功能的发挥。计算结果同时表明,对于文中型号火炮,距离内壁15 mm是该型火炮的报警测温探头安装的最佳位置。若弹药装填入膛的最大温度允许值为170℃,则该点报警温度为159℃,

Abstract: The alert temperature of gun tube was calculated by method of real-time temperature and method of delay-time temperature and the two methods were compared. The influences of the fire mode and the environment temperature on the ascertainment of alert temperature were analyzed. The simulate results show that the error of alert temperature among different fire modes is larger with outer wall temperature used as criterion, and the performance of gun at other fire modes is limited for ensur?ing safe firing at a certain fire mode; the distance of 15 mm from inner wall is the best location for measuring thermocouple; tne alert temperature is 159 °C at the permissible maximum temperature of the cartridge is 170 °C in the bore.

Key words: engineering thermal physics , alert temperature , real-time temperature , delay-time tem-perature
