不同材料的通风盘式制动器散热特性研究

摘要

主要研究制动盘热量的产生机理以及散热过程，结合ANSYS CFX软件，模拟计算奔驰C200在紧急制动情况下，速度从90 km／h下降到0 km／h的过程中，不同材料的通风盘式制动器的制动盘的热量分布情况，得到不同材料制动盘散热特性，为企业生产盘式制动器提供合理的参考。%This paper mainly studied the heat generation and heat dissipation of ventilated disc brakes of different materials .By use of ANSYS CFX software ,the paper simulated the heat distribution of the brake disc of Mercedes‐Benzes C200 in emergency brake situation from 90 km/h to zero .The study on the different material of ventilated disc brakes reveals the thermal distribution of brake disc materials with different thermal properties .This work may provide a valuable .reference for the brake manufacturers .
