| 摘 要： | 在带有裂纹的轴结构件中 ,当裂纹较小时轴的裂纹参数与其固有频率的变化率相关联。为此计算轴结构件固有频率的变化率去识别裂纹位置和深度 ,从而为轴结构件的改进设计及带裂纹的轴结构件剩余寿命的估算提供理论依据

| Abstract: | The crack parameters are related with the fractional change of the natural frequencies in the cracked shaft when the crack is shallow.So,the calculation of the fractional change of the national frequencies can be used to detect the both location and depth of the cracks.The result will be delivered to the reforming design of the shaft structure components and the rest life estimation of them with the cracks. |
