RESEARCH ON METHODS OF DYNAMIC MODELING AND SIMULATION FOR MORPHING WING AIRCRAFT

摘要

The purpose of this paper is studying the multi-mode dynamic modeling and dynamic response simulation of a morphing wing aircraft. By using the theory of Dynamics of Multi-body Systems, considering the morphing wing aircraft as full multi-rigid-body systems, the dynamic equations in vector form for every rigid-body are derived. This paper adopts a modular approach to build the nonlinear numerical simulation model, utilizing the Simulink module in the Matlab software. The nonlinear numerical simulation is applied to investigate the characteristics of dynamic response in multi-morphing mode, specifically analyzing the control efficiency of the asymmetry morphing of wing. The results of the numerical simulations show the correctness and feasibility of this method of modeling.
