| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 98 === The purpose of this study is to investigate unexposed temperature distribution of a standard fire door under different temperature curves by numerical simulations. In this paper, the finite element method by the software ANSYS is used for numerical simulation tool. We appropriately simplified the complicated structure of fire door and used the different boundaries to test fire resistance. Investigate the effects on unexposed temperature distribution with different parameters, such as the coefficients of conduction, convection and radiation. For the program verification, the Wakili's adjustable door frame is used as the experiment model. The results of the numerical simulation compared with the experimental data. It indicate the finite element software can well predict the temperature distribution. Finally, a 120A fire-safety door is designed to study the temperature distribution under different time-temperature curves. It can be concluded that the conductivity of meterial is an important to unexposed temperature distribution. The temperature ratio factor between different temperature curves will not be affected by the material coefficients.
