摘要
依据制动器制动过程中盘内温度过高会导致制动失效的理论,从采煤机工作原理和工作状况的基础研究出发,对采煤机制动器进行了材料和力学分析,利用有限元模拟了采煤机多盘制动器盘内制动温度的变化状态和特性,分析了制动器制动过程中盘内温度的变化对采煤机的正常工作状态和制动性能带来的影响,分析结果对采煤机制动器的结构设计和安全使用提供了可靠的参考依据。
According to the theory of brake failure caused by over-temperature in the process of brakebraking, starting from the basic research on Working principle and working condition of shearer,material and mechanics analysis of shearer brake was carried out. The finite element simulation, thechanging state and characteristics of the brake temperature in the multi-disc brake plate of a coalshearer were analyzed. The influence of the change of the plate temperature on the normal workingcondition and braking performance of the shearer was analyzed when the brake was braked. Theanalysis results provides a reliable reference for the structure design and safe use of the brake.
