本文主要研究井塔整体振动的固有频率和在塔上机电设备激励下的响应,也讨论了井塔计算模型的简化方法。计算井塔响应时,使井塔受单位幅值正弦激振力的作用,在计算机上对井塔响应进行扫频计算,输出井塔频响曲线或频响表格。报据这些曲线和表格,可以了解该井塔在各种频率和幅值的正弦激振力怍用下的响应情况。采用本文所述的计算过程编制的小型专用程序,可在中小型计算机上进行计算,不但机时少,费用低,而且计算精度也是令人满意的。
In this paper, we mainly study the natural frequencies of the entire tower and the response of the tower under mechanical and electrical excitation. We also discuss the simplified method of calculating the well tower. When calculating the response of the well tower, the well tower is subjected to sinusoidal exciting force per unit amplitude. The computer calculates the well tower response sweep frequency and outputs the well tower frequency response curve or frequency response table. According to these curves and tables, you can see the response of the well tower under sinusoidal excitation force of various frequencies and amplitudes. The small dedicated program compiled by using the calculation process described in this article can be calculated on small and medium-sized computers. It not only has less machine time, low cost, but also has satisfactory calculation precision.
