THERMOMECANIQUE DES DISQUES DE FREIN Application du Code de Calcul ANSYS v11.0

Abstract : The object of this thesis is to present a study of thermomechanical behavior of the automobile discs brake for the prediction of their resistance to fatigue. The numerical strategy of calculation is rests on computer code Ansys v. 11. This last which is based on the finite element method and which has management algorithms frictional contact is used to simulate in the braking application, the behavior of mechanism in spite of its complexity. At first, presented an analysis of thermal phenomena operating in a disk brake on (heat flux generated by friction, high thermal gradients, temperature rise).This modeling is carried out by holding account the influence of certain number parameters such as the type of braking, cooling mode, materials designs. Then, a study of purely mechanical dry contact between the disc and pads is developed with a good prediction becomes a major stake for the industrialists while modeling the loading and the boundary conditions around the disc .We used the same computer code to visualize displacements, total deformations in the disc, shear stresses, Von Mises stresses and, the tools of contact pads while carrying out a parametric study such as (Young's modulus pads, coefficient of friction, loading type, rotational speed of the disc..) to see its sensitivity on the calculation results. Thus, the analyzes done on the thermal and mechanical behavior of these prototypes that show that these types of technological solutions represent real areas for improvement that meets the need of the engineer in charge of the design of the brake discs.
