Axial dynamic load identification of hydraulic turbine based on Chebyshev orthogonal polynomial approximation

An analysis method is proposed to identify axial dynamic loads acting on the Francis turbine based on Chebyshev orthogonal polynomial expansion theory. Dynamic loads are expressed as functions of time and polynomial coefficients. The dynamic load identification model is constructed through discretiz...
