| Abstract: | A study was developed on the dynamics Finite Element Simulation of some light aircraft using dynamics analysis theory, based on its CATIA 3-D model, built the dynamics analysis models of wing, fuselage, horizontal tail,vertical tail, joints that connects the parts of the 3-D model and other structures. This paper summarized the design features, force transfer and load carrying mechanism of the aircraft, formulated principles of the simplify of the dynamics analysis model, briefly introduced the special element used in the mode. |
