摘要
采用伽辽金法分析计算空气预热器烟风道外壳平板壳体的弯矩和位移 ,确定烟风道平板的最小许可厚度。并由弹性力学方法进行了烟风道平板壳体的振动分析和膨胀节设计 。
In this paper, bending couple and deflection of rectangular plates in smoke flue of airheater are calculated using Galerkin mothed, and required minimum thickness of the steel plates are determined.The design of expansion joints and vibration analysis for smoke flue shells are made by the elastic mechanics,As a result the parameters for free vibration frequency of plates are obtained.
