摘要
以电磁制动器制动过程中的热力学分析为理论基础,采用ABAQUS软件建立电磁制动器的有限元模型,开展基于制动盘表面温度分布和制动盘应力变化分析的电磁制动器热力学仿真分析研究。仿真结果表明:制动盘摩擦环附近的平均温度达到最高值98℃,满足矿井轨道机车制动性能要求;制动盘内环边缘在结构设计上存在不合理,可进行结构优化。该研究对有效掌握并控制制动器温度的上升、保证制动器满足防爆安全稳定的可靠性要求具有重要意义。
Based on the thermodynamic analysis of electromagnetic brake, the finite element model of electromagnetic brake is established by using ABAQUS software. Based on the analysis of the surface temperature distribution and the stress variation of the brake disc, the thermodynamics simulation analysis of the electromagnetic brake is carried out.The simulation results show that the average temperature near the friction ring of the brake disc reaches the maximum value of 98 ℃, which meets the braking performance requirements of the mine track locomotive, and the inner ring edge of the brake disc is not reasonable in structure design, so the structure can be optimized. This research can effectively grasp and control the rise of brake temperature, and ensure that the brake meets the reliability requirements of explosion-proof, safety and stability. It is of great significance.
