Application of Finite Element Connection Method of Unmanned Aerial Vehicle
The calculation method of inertial relief is verified to address the connecting different structures in finite element modeling of complex aircraft.Based on the complete structure platform of an unmanned aerial vehicle,three finite element connections methods of 1d element,contact and common node are adopted to connect different structures.The modeling and calculation efficiency of each method are compared,and the calculation results are verified by experiments,which conclude that the 1d element connection method is the most efficient connection method in line with the requirements of engineering.
