Design Optimisation and Analysis of a Quadrotor Arm Using Finite Element Method

The structural analysis of quad rotor frame is important since it has to withstand the forces due to aerodynamics and gravitational force due to the mounted weights. Design optimization based on finite element analysis provides an efficient methodology to meet the desired objectives related to structural elements. In the present study, design optimization based on response surface methodology has been used to optimize the shape of the arm used in the quad rotor. The objectives considered for the study include minimization of Von Mises stress and total deformation. The goal driven optimization used in ANSYS WORKBENCH has been employed for the study and arm has been redesigned to meet the set goals.
