摘要 采用能量方法研究了含有裂纹缺陷的弯曲梁结构自由振动特性,分析模型为无限自由度的连续体非均匀弹性悬臂梁,裂纹的深度与位置是任意的。由 Rayleigh-Ritz 方法给出了结构前三阶固有振动频率的数值结果。 Free vibration characteristics of a bending beam with cracked defectiveness is presented.The analytical model is a continuous non-homogeneous cantilever with a crack,the depth and location of the crack are variable. The first three natural frequencis of the beam are given by using Rayleigh-Ritz method.
