摘要：
A modelling method for the vibration analysis of rotating pretwisted blades with a concentrated mass is presented in this paper. The blade has an arbitrary orientation with respect to the rigid hub to which it is fixed. The equations of motion are derived based on a modelling method that employs hybrid deformation variables. The resulting equations for the vibration analysis are transformed into a dimensionless form in which dimensionless parameters are identified. The effects of the dimensionless parameters on the modal characteristics of the rotating blade are investigated through numerical analysis. (C) 2001 Academic Press.
