| Abstract: | The method for analysing the vibration characteristics of composite blades is presented. Based on the continuum mechanics theory, a new isoparametric curve beam element is set up. The shape functions of every point on the beam are derived in detail and the integral techniques of complex aerofoil are discussed. The new element can model the cross section and the plyment of composite. The calculation time will be widely reduced if this element is used to analyse the vibration characteristics and response of blades. Certainly the new element is fit for the analysis of the other thin-walled structures. Numeral examples show that the results are coincident with the test. |
