The Influence of the Braking Disc Ribs and Applied Material on the Natural Frequency
Oday I. Abdullah,Nadica Stojanovic,Ivan Grujic 한국정밀공학회 2022 International Journal of Precision Engineering and Vol.23 No.1
One of the important problems for which must be found an optimal solution is the noise that originate from vehicles. In this research paper, it was investigated deeply the effect of ribs shape and type of material on the noise of ventilated braking discs. Four different ventilated braking discs were selected to achieve the numerical analysis, all these brakes have the same overall dimensions, except the ribs shape is different. The materials used in this work are the cast iron, AMC and CCM for all four discs. The main aim of this paper is to find the optimal ribs shape, as well as the manufacturing material for the braking disc by applying Taguchi method. The percentage share of the ribs shapes as well as of applied material influence on the noise generation, were determined by applying Analysis of Variance—ANOVA. Finally, it was found that the material influence is most significant with 74.48%, while the ribs shape influence on the noise generation is 24.24%. The most optimal results obtained for the 2nd model which was made from CCM, compared with other suggested models.
