摘要
为推导闸瓦磨损率的数学模型,利用X-DM型调压变速摩擦实验机,开展闸瓦材料与带式输送机制动钢盘对摩试验,采集闸瓦磨损量、比压和温度等试验数据;基于这些试验数据,运用现代摩擦磨损理论、非线性拟合方法及数理统计技术,综合考虑多方面因素的影响,建立科学、适用的磨损率数学模型;利用F检验方法对建立的模型进行显著性检验可知,该模型具有数学上的严谨性,可为带式输送机制动装置设计及闸瓦研发提供重要依据。
To deduce the mathematic model of the wear rate of the brake shoe, X-DM pressure-regulating and velocity-variable friction tester was applied to carry out the test for the friction between material of the brake shoe and the braking disc of the belt conveyor, and the test data about wear loss, specific pressure and temperature were obtained. Based on these test data, modern friction and wear theory, nonlinear fitting method and mathematical statistics technology were applied to establish scientific and applicable mathematical model of the wear rate after overall considering the influence of multiple factors. In addition, F checking method was applied to conduct significance test for the established model. The results showed the model was of mathematical rigourism, which offered important reference for the design of the brake of the belt conveyor and the development of the brake shoe.
