固支条件下悬挂塔的自振频率与支承高度

Calculating the Natural Frequencies of Clamped Hanging Tower and Support Position

重点介绍了固支条件下悬挂塔自振频率的计算方法 ,并用有限单元法予以论证 ,取得了很好的结果。在此基础上讨论了最适宜的支承位置 ,还提出了等截面悬挂塔自振频率的简捷计算公式。

A method for calculating the natural frequencies of clamped hanging tower was presented in this paper.The calculation results were compared with that of finite element analysis, and the comparison shows that they were in good agreement. On this basis, the influence of support position on the natural frequencies of clamped hanging tower had been discussed. In addition, a simplified formula was given for constant cross-section hanging tower.
