摘要：

Based on the transfer matrix method and Forman equation, a new method is proposed to conduct the modal and fatigue life analysis of a beam with multiple transverse cracks. In the modal analysis, the damping loss factor is introduced by the complex elastic modulus, bending springs without mass are used to replace the transverse cracks, and the characteristic transfer matrix of the whole cracked beam can be derived. In the fatigue life analysis, considering the interaction of the beam vibration and fatigue cracks growth, the fatigue life of the cracked beam is predicted by the timing analysis method. Numerical calculation shows that cracks have a significant influence on the modal and fatigue life of the beam. © 2018, Editorial Department of Transactions of NUAA. All right reserved.
