摘要

为研究钢丝绳输送带的压陷阻力特性,以托辊、输送带、牵引导板为压陷阻力测试系统的模型,以Ansys中Mooney-Rivlin定义橡胶覆盖层属性、以Isotropic定义钢丝绳属性,将覆盖层与钢丝绳、覆盖层与牵引导板、钢丝绳与牵引导板间设置为Glue约束,模拟钢丝绳芯橡胶输送带,仿真研究了St2000型输送带的压陷阻力特性,分析结果表明:当托辊压下力小于100 N时,压陷阻力几乎为0,受覆盖层粘弹性和滞后性的影响,压陷阻力随压下力的增加呈非线性增加,当压下力均值达到3 000 N时,压下阻力均值为26.3 N。对St2000输送带的压陷阻力进行实测,测得在3 000 N压下力作用下,压陷阻力均值为27.2 N,实验结果表明仿真模型具有一定的有效性,研究结果为橡胶输送带的耗能分析与计算提供基础。

Abstract

In order to investigate pressure resistance character of steel conveyor,The roller,conveyor,and traction guide were treated as test system model. The model of Mooney-Rivlin was defined as rubber covering attribute. Attribute of wire rope was defined as Isotropic. Covering and wire rope,traction guide and covering,wire rope and traction guide were set to glue binding. Rubber belts of wire rope core was simulated. Properties of pressure resistance of the St2000 type conveyor belt was researched. The numerical analysis results is that reduction pressure resistance close to 0 when the roller pressure are less than100 N. Pressure resistance nonlinearly increase with the increasing of pressure as the effect of cover layer of viscoelasticity and the hysteretic nature. The mean value of pressure resistance are 26. 3N when the mean value of pressure are 3000 N. Pressure resistance of St2000 type conveyor belt is measured. The results show that the mean value of pressure resistance are 27. 2N when the mean value of pressure are 3000 N. The results of experiments show that the simulating model is effective. The results provide basic for energy dissipation calculation of rubber conveyor belt.
