| 摘 要： | 为更好地分析复杂飞机库钢结构平移门门扇在荷载作用下的内力和位移,按规范要求选择、验算结构尺寸,利用MIDAS（GENV6.3.2）结构设计有限元分析软件,对香港飞机库钢结构平移门门扇在自重、风荷载作用下采用静态分析方法进行计算,对固有频率和模态振型采用模态分析方法计算,用迭代法提取前6阶频率。结果表明,门扇的最大弯曲应力低于材料的屈服应力,且抗震性能良好。

| Abstract: | In order to analyses the stress and displacement of the wing of steel translatio n door and select physical dimension by code, finite element methed software—— MIDAS(GENV6.3.2) is utilitied to calculate the stress and displacement under the self weight and wind loading by static analysis means . Natural frequency and vibration modes are calculated by modal analysis and front six frequencie s are extracted by iteration method. The results show that the door’s maximum bending stress is much lower than its yielding strength,and it has good aseismat ic property. |
