Development of Prototype-Model and DesignModification,Analysis of Aircraft Wheelhub

Abstract

Design and implementation of new aerospace elements which requires the use of 3D-CAD modeling techniques
and rapid prototyping, which makes it possible to significantly accelerate the deployment of new solutions. In this paper
we demonstrate, one of the rapid prototyping techniques FDM is used to produce the working model of Aircraft Wheel
hub. Meanwhile the task is to reduce the stress concentration in the Wheel Hub due to body weight of aircraft and other
loads on the wheel hub. For design of the wheel hub Catia V5 is used. It is analysed by using the ANSYS. While analyzing
the stress, stress concentration is found in the fixed regions (location of its bolts). The stress concentration is checked in
three ways and selecting the one which gives the optimum stress concentration. The three ways are Design modification,
Material changing without design modifications, material changing with design modification. From these three ways we
will find out optimum changes in stress concentration. After selecting the best design and converting that 3D-CAD file
into STL file or saving file in STL form. That STL file is used for direct developing of prototyping model by using FDM
process.
