Embodiment Construction
[0124] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0125] In the prior art, the multibody system transfer matrix method (MSTMM) was established by Academician Rui Xiaoting and his team for multibody dynamics analysis. This method can realize general multi-body system dynamics research, and its high computational efficiency can be easily applied in engineering. The invention is applied to the calculation of the vibration characteristics of the airfoil, which can realize the fast modeling and fast calculation of the aeroelastic model of the airfoil.
[0126] The invention uses MSTMM to calculate the vibration characteristics of the three-dimensional wing, and according to the wing vibration shape calculated by the MSTMM, proposes the idea of mo...
