Optimization of the Thermal and Mechanical Behavior of an Aeronautical Brake Disc using the Design of Experiments Approach

Résumé

The construction of the brake discs is the subject of numerous studies in the field of automotive, railway and aviation. Indeed, it involves the safety of passengers, which is a primary criterion. The research has focused on the contact of two rubbing parts. So various phenomena may occur such as the rise in temperature, wear and noise emissions. In this study, we chose different geometric disc models designed in 3D using Solid Works software, which are imported ANSYS to do the evaluation of the heat transfer coefficients using ANSYS CFX code. Then we proceed to the analysis of the transient thermal behavior of each model and the determination of the equivalent stress.The simulation results provided by the ANSYS software are used to establish several designs of experiments for each one we write the corresponding mathematical model, then we apply ANOVA method and fisher ‘s analysis to determine the influential factors.DOI: http://dx.doi.org/10.5755/j01.mech.24.2.19110
