Modélisation thermomécanique par ansys du contact dans un système disque freins d’automobile

Abstract

Design study of automatichydraulicbraking system. 22% of road accidents are caused by brakefailure. Therefore, the braking system is one of the most important safety and protection tools in the car, both for passengers and pedestrians, whendriving on the road, and also in machines and mechanicalsystemsso attention shouldbepaid to this part. Brakes are one of the mandatory components of a moving machine. Anymoving machine or vehicleneeds a brake to slow down and stop. Among the main types of brakesused in modern cars are hydraulicbrakes, Fred Dosenbergdevelopedhydraulicbrakes in his racing cars in 1914 and Donsbergbecame the first car brand to use thistechnology in passenger cars in1921;hydraulicbrakeis a braking system based on a brakefluidthattransfers pressure from the control mechanism to the brakingmechanism. The purpose of thisstudyis to compare the spring force with the brake transmission force, as well as to compare the brake force torque with the pinion transmission torque. It alsoaims to draw the hydraulicbrakeusing Microsoft Visio program, and then use SolidWorks to calculate the different stresses that can beapplied to the disc braketooth for certain materials.
