摘要
现代机枪重量较轻,要达到理想的射击精度就必须保证良好的动力匹配关系.机枪在射击过程中,枪管温度的升高直接影响机枪的动力特性.对某型机枪射击过程中枪管温度场及其对机枪动力特性的影响进行了分析,结果表明,温度变化对机枪动力特性改变的影响较小.
To get ideal firing accuracy of modern machine gun with light mass, a good dynamic matching relationship must be guaranteed. In firing of machine guns, temperature field of barrel affects the dynamic characteristic directly. In this paper, the temperature field of barrel in firing and its influence to machine gun are analyzed, which shows that the change of temperature field to machine gun＇s dynamic characteristic is of less influence.
