Finite element modeling for structural strength of quadcoptor type multi mode vehicle

摘要

Quadcoptor (QD) type multi mode vehicle is modeled for the structural strength using finite element method (FEM). Static as well as dynamic mass and stiffness matrix were developed for key component of such vehicle that includes base plate, mounting frame, arm, support frame, propeller and wheel set. The components, thus generated are preprocessed for meshing, material selection, constraining, loading. The boundary condition is set and mesh convergence is tested before solving the model. The results, such as deformation, von Misses stress are analyzed for each component as well as for the upper half of the multi mode vehicle. The results depict the critically stressed zone of various key components of QD. (c) 2016 Elsevier Masson SAS. All rights reserved.
