摘要
为解决气动弹性中存在的线性和非线性气动力降阶建模问题,采用线性的ARAM模型和非线性的Kriging模型构建分层模型。通过输入的小幅和大幅激励信号及其非定常气动力响应,得到分层非线性动力学模型。算例结果表明,分层模型可以精确模拟复杂非线性气动力。
In order to solve the linear and nonlinear aerodynamic reduction modeling problems in aeroelasticity,a layered model was constructed by using ARMA model and Kriging model.The layered nonlinear aerodynamic model was obtained by the input small and large excitiation signals and their unsteady responses.The numerical results show that the layered model can simulate the complex nonlinear aerodynamic forces accurately.
