摘要

考虑到刮板输送机的工作环境复杂、恶劣,链条牵引刮板群推移物料时不仅会引起链条的纵向振动,而且由于物料突然增加、异物卡死等因素容易造成卡链故障,通过有限元方法将链条传动系统离散并建立了基于Kelvin-Vogit模型链条体系动力学模型,并使用理论计算公式结合实测数据确定了刮板链条的刚度系数。通过数值仿真软件Matlab对刮板输送机在卡链故障工况下进行数值仿真,得到了设备不同位置卡链时链条速度变化与张力分布特性。最后通过实验的方法测得数据与仿真结果比对,测试数据与仿真结果基本一致。

Abstract

Scraper conveyor is always working in complex and poor working environment. It will cause the longitudinal vibration of chains when the scraper group goes on material dragged by the chains,and the fault of seizing the chains caused by a sudden increase in material,foreign body stuck or other factors. Discrete the chain transmission system and establish the system dynamics model of the chain based on Kelvin-Vogit model through the finite element method. Determine the stiffness coefficient of the scraper chain combined with the theoretical calculation and actual measurement data. Carry out the numerical simulation on the fault condition of seizing the chains through the numerical simulation software. Obtain the speed change and tension distribution rules of the chain on the different seizing position. Finally,it is found that the experiment data and the simulation results are basically consistent compared experiment data with simulation results.
