带导向支撑塔设备强度、挠度的计算

Calculation of Strength and Deflection of the Tower with Guide Support

采用公式解析法和有限元建立梁模型的方法分别计算塔设备在风载荷、地震载荷作用下的弯矩和挠度。对比发现:公式解析法简单、易操作,但仅适用于塔体无变径、等厚且仅有一处支撑的模型;有限元软件建立梁模型的方法能够更加准确地模拟塔设备的受力情况,得到更加精确的结果。

For specific instance,the formula analysis method and establishing beam model by finite element software were adopted to respectively calculate moment and deflection of the tower under wind load and earthquake load.Comparison results showed that,the formula analysis method is easy and has operability but it only suits to the tower with equal diameter and equal thickness and only one guide support;and the method of establishing beam model by finite element software can accurately simulate the force on the tower and the simulation result is more precise.
