摘要
本文对工业中的排塔的自振特性进行了有限元分析,并通过排塔模型实验对有限元计算结果进行了验证。通过实验与计算结果分析,提出了计算排塔平面内振动一阶自振频率的简化公式。
In this paper, the finite element methed was applied to ahalyze the natural vibration period of the coupled in - line towere used in engineering. Then, the experiment are carried oul for the model to verified the analysis, result. Based on thase result,the simplified formulae to calculate the first order natural frequeccy of the coupled in - line towers were presented.
