|Abstract:||It is well-known that lower modes of vibration are responsible for a high percentage of the dynamic response. In this paper, the task of simulation of the dynamic response of the composite wind turbine blade on the basis numerical realisation of a developed low dimensional beam type model is considered. From the governing system of differential-algebraic equation of the simpliﬁed beam type model of the blade, and using the mode superposition approximation, the system of linear ordinary differential equations with respect to the coefﬁcient functions of the modal representation was obtained. The developed program codes allow to simulate low frequency bending vibrations of wind turbine blades under different steady-state and transient loadings. The comparison of the simulation results obtained by the proposed simpliﬁed blade model with the results of the direct Finite Element Method (FEM) simulation shows their close agreement, which conﬁrms the adequacy of the developed model and its mode-based approximation to the level of the requirements necessary in engineering practice. The presented approach to the creating low-dimensional simpliﬁed models of slender structures can therefore be useful in different ﬁelds of aerospace, civil, mechanical, and transport engineering.|
