Optimization of ventilated disc brake vanes for heavy duty vehicle

Abstract

The important task for automotive engineering researchers today is to design such brake system that under all operating conditions (emergency braking, mild short-term braking and mild long-term downhill braking) has stable performances. Today, all the highest performance car manufacturers have ventilated disc brakes all around for the shortest stopping distances. However, air disc brakes for heavy duty vehicles are not far behind them. The study of the influence of the dimension of vanes to the mass of ventilated disc and deformation that occurs in the braking process is performed in this paper. Optimization process is performed in ANSYS software, by using Screening method. Application of virtual experiments during the early stage of product development provides money saving during manufacturing. Also it is possible to make a modification of the product and certainly produce such a product which will enable the manufacturer a secure market position.
