• Swept (axially leaned) blade concept in fan and compressor design is known as the effective way to improve aerodynamic performance, but other hand special care may be taken for bladed disk vibration problem because the Coriolis effect can no more be neglected in such a rotor and may gives the significant change in forced response of bladed disk assemblies. Some authors study on this problem analytically and experimentally, and obtain the results that the Coriolis-induced natural frequency splits affect the same effect as the splits caused by blade mistuning. But their study was only for simple shaped disk configuration and so the impact for practical bladed disk structural design are not known sufficiently. In this paper, vibration analysis with Coriolis effects were performed for swept and conventional fan bladed disk assemblies whose configurations are practically assumed and compared to their non-Coriolis counterpart.
