VANES SHAPE OPTIMIZATION OF VENTILATED DISC BRAKES FOR HEAVY DUTY VEHICLES

Abstract

Braking system represents a very important system for all types of motor and trailer Vehicles. The basic task of the braking system is reducing the vehicle speed until it stops or slows down to a lower speed. Furthermore, the braking system should also ensure that the vehicle is kept in a steady state. To achieve that the vehicle has a shorter braking distance, it is necessary to reduce the flywheel masses. The purpose of this paper is to reduce the weight of the venting disc, which is partly responsible for the value of braking distance achieved. Besides that, it must be ensured that deformations and stresses remain in the limits. Optimization is performed by ANSYS software package. The application of virtual experiments gives quick answers in developing a new or improving the already existing part. It also enables corrections of the product itself, as well as competitiveness on the market.
