Abstract
An effort has been made to develop a general aeroelasticity model for flexible multibody systems in a companion paper [H. Du, D. Hitchings and G. A. O. Davies, Comput. Struct. 48, 387–395 (1993)]. The methodology in multibody dynamics formulation has been made full use of in order to create a model of great modelling flexibility. The developed multibody aeroelasticity model is used in this paper to investigate the aeroelasticity stability problems of helicopter blades. Extensive numerical examples are presented. The results obtained are compared with the existing reliable results to verify the model. Then, the modelling flexibility is demonstrated by making use of the six degrees of freedom of the moving base, which are essential in multibody dynamics formulation. Results show that the multibody aeroelasticity model developed and the ideas suggested have great potentials in aeroelasticity modelling of multibody systems.
