摘要

为了研究盘式制动器在紧急制动工况下瞬态温度场的变化,利用Starccm+计算出的随转速变化的对流换热系数,使之与解析法对比验证。将其作为瞬态计算的边界条件,结合实测摩擦系数--车速试验数据,通过Abaqus分析制动盘径向、周向及轴向温度场、应力场的分布特性;通过台架试验与仿真结果对比,仿真温度与试验温度结果具有良好的一致性。研究结果表明:盘式制动器在制动过程中温度场及应力场存在复杂的耦合关系,建立CFD和CAE联合仿真模型可以为制动盘温度场的分析提供了一种有效方法。
        In order to study the transient changes of the temperature field for disc brake under emergency braking conditions,by using the calculated heat transfer coefficient of convection with speed change by Starccm+,it is compared and verified with the analytic method. The calculated convection heat transfer coefficient is used as the boundary condition for transient calculation,combined with the measured friction coefficient and vehicle speed test data,the temperature field and stress field of radial direction,circumference and axial direction was analyzed by Abaqus.Through the bench test and simulation results,simulation temperature and test temperature results have good consistency. The results show that there is a complicated coupling relationship between the temperature field and the stress field of the disc brake during braking,it can provide an effective method for the analysis of the temperature field of the brake disc by establishing the co-simulation model of CFD and CAE.
