Rotor Design and Analysis; A Technique Using Computational Fluid Dynamics (CFD) and Heat Transfer Analysis

Abstract

<div class="htmlview paragraph">Rotor geometrical design and manufacturing are much less complicated in comparison to other brake components due to its symmetry and simplistic features. However, engineering the rotor to meet the thermal requirement performance is a challenging task for rotor engineers.</div> <div class="htmlview paragraph">This technical paper focuses on the management of heat conjugate modeling (CFD), thermal film coefficient, rotor coning, rotor temperature (fading cycle), thermal stress, and fin design to optimize rotors. From the initial concept design, effective use of CFD analysis, Abaqus thermal structural analysis, rotor modal separation and a rotor empirical history database can be applied to the rotor development process.</div>
