Abstract EN
We propose an accurate approach, based on the precise integration method, to solve the aeroelastic system of an airfoil with a pitch hysteresis.
A major procedure for achieving high precision is to design a predictor-corrector algorithm.
This algorithm enables accurate determination of switching points resulting from the hysteresis.
Numerical examples show that the results obtained by the presented method are in excellent agreement with exact solutions.
In addition, the high accuracy can be maintained as the time step increases in a reasonable range.
It is also found that the Runge-Kutta method may sometimes provide quite different and even fallacious results, though the step length is much less than that adopted in the presented method.
With such high computational accuracy, the presented method could be applicable in dynamical systems with hysteresis nonlinearities.
