摘要
为解决矿用带式输送机驱动功率经典算法精度低的问题,并提高矿用设备能量利用率,运用WLF原理,用实验和模型手段定量描述高分子材料动态性能。利用精确(2D)有限厚度模拟方法建立输送带压陷滚动阻力模型,分析压陷滚动阻力与正压力、输送带厚度的关系,以应用实例说明低阻力输送带在长距离输送系统中的优势。
In order to solve the problem of low precision of the classical algorithm of mining belt conveyor driving power,and to improve the energy utilization rate of mining equipment,using the principle of WLF,quantitatively described the dynamic performance of polymer materials by experiments and model means.The accurate(2D)finite thickness simulation method was used to establish the rolling belt indentation resistance model.The relationship between the indentation resistance and the positive pressure and the thickness of the belt was analyzed.The advantages of low-resistance belt in long-distance transportation were illustrated by application example.
