基于静风压的独立避雷针横截面优化

Cross Section Optimization of Lighting Rod Based on Static Wind Pressure

避雷针作为一种常用的防雷设备,应用范围广,装备量大,在安全生产中起着非常重要的作用。避雷针是户外工作设备,当其结构体积较大时需要考虑风对其强度的影响。文中通过实例,介绍了一种通过有限元方法计算避雷针静风压下的横截面优化方法,为避雷针方案设计和安全生产提供了依据。

Lighting rod, which is used in a wide range and equipped in a large quantity as a common lighting protecting equipment, acts a very important role in the safety production. As lighting rod is a kind of outdoor equipment, while the volume of the lighting rod structure is large relatively, the impact of the pressure on the structure of the lighting rod loaded by the wind must be considered. A method by finite el- ement, calculating the cross section of the lighting rod under the force of static wind pressure, is intro- duced in this paper, which provides a basis for the lightning rod device design and safety production.
