对高速列车上使用的制动盘进行强化散热设计,采用在制动盘摩擦面开导流槽的方法,使其能够对制动盘摩擦面起到进一步散热的效果。根据摩擦学、流体力学、传热学原理对制动盘导流槽进行设计并分析,采用计算流体动力学软件FLUENT分析了制动盘摩擦面导流槽内流场的分布情况,通过ANSYS10.0有限元软件对制动盘的温度场进行了仿真分析。最终验证了在制动盘表面开导流槽存在强化散热方面的作用。
On the high-speed train brake discs used to strengthen the cooling design, the use of brake disc friction surface to open diversion groove method, it can brake disc friction surface to further cooling effect. According to the principles of tribology, fluid mechanics and heat transfer, the flow field of the brake disc was designed and analyzed. The distribution of the flow field in the friction disc of the brake disc was analyzed by CFD software FLUENT by ANSYS10. 0 finite element software simulation of the temperature field of the brake disc. Finally, it verifies the role of the guide groove in the surface of the brake disc to enhance the heat dissipation.
