摘要
为提高矿用电机车井下运输的安全性,对现有的手轮闸瓦制动装置进行了分析,针对其制动性能的不足,提出了一种气动通风盘式制动装置方案。参考列车牵引制动相关公式与理论,对其制动性能进行了计算验证;同时,运用有限元软件Abaqus对其制动过程进行了仿真分析,得到了通风盘式制动器的温度场分布云图以及相应节点的温度变化曲线;并进行了试验测试。结果表明,该制动装置可有效提高矿用电机车的制动性能,缩短制动距离,且能够满足MT/T 1064—2008技术条件的要求。为今后矿用电机车制动装置的改进提供了依据,具有一定的应用价值。
In order to improve the safety of underground transportation of mine electric locomotive,the existing hand wheel brake shoe brake device is analyzed. Aiming at the shortage of braking performance,a kind of pneumatic ventilated disc brake device is proposed. Referring to the formula and theory of train traction braking,the braking performance is verified by calculation. At the same time,the braking process is simulated and analyzed by the finite element software Abaqus,the temperature field distribution nephogram and the temperature variation curve of the corresponding node are obtained. Finally,the test is carried out. The results show that the braking device can improve the braking performance of mine electric locomotive effectively,shorten the braking distance,and can meet the requirements of MT/T 1064—2008 technical conditions. It provides the basis for the improvement of the braking device of the mine electric locomotive in the future,and has certain application value.
