Numerical Simulation of Continuous Gust Based on Harmony Superposition Method
The discrete gust dynamic response is an important link in the loads design process of e-lastic aircraft.As the discrete gust is often matched by functional curves,with single confidence and lack of high frequency information,a numerical simulation method based on harmony superposition was proposed which converted the Von Karman model into the time-domain random gust.The Von Karman mode is more applicable to the elastic aircraft.Then the gust model before and after the nu-merical simulation was used to calculate the gust dynamic response of the wing.By comparing the re-sult of the dynamic response,it was root-mean-square error that the deviation of the wing's shear-ing,bending moment and torque was within 5%.The accuracy of the numerical simulation method based on harmony superposition was demonstrated.
