用修正的Dunkerley公式计算结构的基频

To Calculate the Fundamental Frequency of the Structure Using Revised Dunkerley Formula

用修正的Dunkerley公式计算了二振系的基频,结果表明,用修正的Dunkerley公式计算结构基频,基精度明显高于Dunkerley公式.

The fundamental frequency of two vibrationsystems is calculated using revised Dun-kerley formulan this paper,the results indicate that the precisions higher than that using Dunker-ley formula.
