| Abstract: | In this paper, taking a naval gun for example, the finite element method in space field and in time field are employed to solve problem of thermal-stress coupled field during continual firing. The special law of the dynamic characteristics of thermodynamics of the barrel are also analyzed under the thermal shock and pressure shock. Based on the disadvantage of these thermal shock effects, relevant measures of amelioration was presented. The conclusions in this paper are valuable to design gun barrel and the service of a naval gun. |
