| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 100 === This paper is to investigate the unexposed temperature distribution and deformation of a fire door with different materials in a furnace by numerical simulations. The finite element method by the ANSYS is used for the numerical simulation tool. In the part of verification, first, the numerical simulation comparison with the exact solution of simply supported circular plate to thermal loading performed by Ugural. Second, the fire door proposed by Tabaddor the effect of radiation is very important in this case. The simulation results is compared well with Tabaddor. It indicates that the finite element software can well predict the temperature distribution and deformation. Finally, the design of a fire door, this study based on the materials choice is investigated. A variety of permutations and combinations for laminate plank board and sandwich board are choice. As much as possible to observe the impact of various insulation materials of fire door, we find out the best of a fire resistance combination for laminate plank board and sandwich board. From the above tests, the following conclusions are given:
(1) In the parameters of structural materials, the thermal expansion coefficient is important factors on deformation of a fire door.
(2) Excluding the chemical reaction, affect the maximum should be the framework of door frame and the skeleton structure of fire door.
