Modeling and Mechanical Vibration characteristics analysis of a Quadcopter Propeller using FEA

Abstract

Abstract Quadcopter is a mechatronic device that has four arms and each arm having a D.C. motor with a propeller. These four propellers provide the thrust to quadcopter, furthermore difference in the angular speed of these propellers is responsible for roll, pitch and yaw motion. The propeller of the quadcopter is subjected to the dynamic loading and vibration during the flight. The present study investigates the vibration characteristics of quadcopter propeller. To investigate the vibration behaviour, three different type of material are analyzed for result comparison. The solid model of propeller was designed in Creo 2.0 and Ansys 16.2 was used for analysis. Modal analysis was performed to find the First 6 natural fundamental frequencies and their mode shape. The frequency variation describes the failure and safe region through colour couture scale under different loading condition. The obtained results are compared and validated with the previous studies.
