Study on Cooling Performance of Braking System Based on Helt Flux Theory

为了能够更加精准的预测乘用车在实际驾驶过程中盘式制中制动盘与摩擦片的温度变化情况，需要对车辆行驶过程中非制动工况的冷却特性进行研究。研究团队根据热通量理论，进行制动系统冷却性能理论推导，并提出“冷却系数”，并通过整车道路试验与惯量试验台分别进行“冷却系数”获取研究，并将“冷却系数”应用至整车制动系统制动盘与摩擦片温度预测。In order to more accurately predict the temperature change of brake disc and friction plate during the actual driving process of passenger cars, it is necessary to study the cooling characteristics of the vehicle during non braking conditions. According to the heat flux theory, Research team conducts theoretical derivation of the cooling performance of the brake system, and puts forward the “cooling coefficient”, and conducts research on obtaining the “cooling coefficient” through the vehicle road test and inertia test bench, and applies the “cooling coefficient” to the temperature prediction of the brake disc and friction plate of the vehicle brake system.
