摘要:
［目的］目前，城市轨道交通车辆的制动盘散热性能有待提升，因此，有必要研究新型散热筋的优化设计方案。［方法］采用有限元分析的数值模拟方法，通过计算机辅助设计软件，建立新型散热筋的制动盘三维模型。提出不同散热筋设计方案，利用有限元分析技术对不同散热筋设计方案进行热分析模拟。通过比较不同散热筋设计在轴装制动盘和轮装制动盘上的热传导效率和散热路径，评估不同散热筋制动盘的散热能力。［结果及结论］轮装直板式散热筋和轴装圆柱式散热筋设计方案均显著优化了散热路径，提升了热量从热源向外部冷却介质的转移效率。散热筋的循环对称设计有效降低了制动盘生产过程的复杂性，同时最大限度地减少了对车轴等相关部件的损伤，能够为列车的安全可靠运行提供保障。

［Objective］At present, the heat dissipation performance of brake discs for urban rail transit vehicles needs to be improved. Therefore, it is necessary to study the optimization design scheme for a new type of heat dissipation ribs. ［Method］By adopting the numerical simulation method of finite element analysis, a three-dimensional brake disc model with new type heat dissipation ribs is established through computer-aided design software. Different design schemes for heat dissipation ribs are proposed, and the thermal analysis simulation for these schemes is conducted by the finite element analysis technology. In terms of heat conduction efficiency and heat dissipation paths on axle-mounted brake discs and on wheel-mounted ones, different heat dissipation rib designs are compared, and the heat dissipation capacities of the brake discs with different heat dissipation ribs are evaluated. ［Result & Conclusion］Both the design schemes of the wheel-mounted straight-plate heat dissipation ribs and the axle-mounted cylindrical heat dissipation ribs significantly optimize the heat dissipation paths, improving the transfer efficiency of heat from the heat source to the external cooling medium. The cyclic symmetric design of the heat dissipation ribs effectively reduces the complexity of the brake disc production process, and minimizes damages simultaneously to the relevant components such as the axles, therefore can provide a guarantee for the safe and reliable train operation.
