摘要

为了研究刮板输送机刮板链条体系的扭摆动态特性,采用有限元法建立了刮板链条体系的动力学模型,通过施加脉冲载荷、阶跃载荷及斜坡载荷对刮板链条体系的动力学问题进行了数值仿真,研究了刮板体系的扭摆特性、链条动力响应以及刮板间动力传递特性。研究结果表明:在承载处刮板产生了较大的扭摆角位移以及较大扭摆力矩,且扭摆角位移幅值以及扭摆力矩由承载处向两侧逐渐减小,研究成果为刮板输送机的动态设计提供了理论基础。

Abstract

In order to investigate torsion pendulum dynamic characteristics of scraper chain system,dynamic model of scraper chain system was established by using finite element method.Numerical simulation was analyzed for dynamic characteristics of scraper chain system by applying pulse load,step load and slope load.Torsion pendulum dynamic characteristics of scraper chain system,dynamic response of chain and dynamic tension transfer characteristic of scraper were researched.The results show that scraper has a big angular displacement at bearing section,and has a big torsion moment.Angular displacement amplitude and torsion moment amplitude gradually reduce from bearing section to the sides.The results provide theoretical basis for dynamic design of scraper conveyor.
