摘要
本文讨论了具有裂缝的简支梁，其固有频率的变化规律与裂缝所在部位的关系。并推导出一种判断裂缝位置的泛函分析法。
The natural frequencies of a simply supported beam with a crack are discussed, The relationship between the rates of change of the natural frequency and the position of a crack is revealed and evaluated.A functional analysis method to determine the position of a crack is proposed.
