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。
In order to deduce the mathematic model of the brake shoe wear rate, X-DM pressure-controlled variable speed friction test machine was used to test the brake shoe friction between the brake shoe material and the belt conveyor, and to collect the brake shoe wear loss, specific pressure and temperature test Based on these experimental data, a mathematical model of wear rate was set up based on modern friction and wear theory, non-linear fitting method and mathematical statistics. The mathematical model of wear rate was established by comprehensively considering the influence of many factors. The model was established by F-test The test of significance shows that the model is mathematically rigorous and can provide an important basis for the design of brake device of belt conveyor and the research and development of brake shoes.
