摘要: In this paper, the forced vibration of a cracked rotor with an open edge crack has been studied by new continuous model for flexural rotors proposed in Ebrahimi et al. (J Sound Vib 333:3522–3535, 2014). The behavior under external excitation gravity and unbalance forces is presented. Since governing equation linear, using superposition principle responses to are calculated separately. Then, total response summing these two responses. Each found modified Galerkin method. effect presence on time response, frequency spectrum, curve orbit diagram analyzed. Results can be used identification rotors.
