Model-based brake disc temperature prediction on high speed testing mode and circuit 2020-01-0214

Brake force of vehicle generated by the kinetic energy of vehicle is transformed into heat energy by using the brake pad materials and friction of disc and heated temperature reflect the disc. At the same time, it is transmitted into the air or around components. Heated temperature cause the problem of fade performance which is happened degradation of friction coefficient between disc and pad materials and cause dramatic pad wear. Therefore, to develop sufficiently obtained thermal capacity of disc dimension is quite important process in initial concept development. In order to approach well concept of development in brake, Thermal capacity of disc should be predicted reliably and precisely. This paper built the brake thermal simulation modeling which is possible to predict the disc capacity based on parameterization of front and rear disc development. And it predicted analytically by using brake thermal simulation modeling for European brake mode generally called by AMS mode which affect big influentially for brake disc capacity design as well as consider the characteristics of high performance vehicle on the circuit. Study is applied front-wheel C-segment of high performance vehicle and the brake disc temperature simulation raised highly reliability for prediction which correlated and compared between temperature analysis and measured data.
