| Abstract: | Thermal analysis refers to the resolution of temperature field and the calculation of thermal stress.In this paper,the object of research is the impact of deck structure under spray hot air flow.By means of the thermal and structural module in MSC software, the thermal analysis was carried out.Thermal theory, simplification of model,mesh plot of FEM and boundary conditions were researched in detail.The results indicate that the influence on structure safety and nature can not be ignored.It also provides reference to correlative thermal load study. |
