Large Belt Take-ups' Dynamic Analysis And Their Optimization Design

With the development of belt conveyor towards long distance,high speed,long earring capacity and large driving power,the effect of the dynamic property on belt conveyor is becoming more and more important.Especially under the condition of starting or stopping.And also,as one of the most indispensable parts in belt conveyor,take-up has an direct effect on safety,reliability and oscillation property of conveyor system on a whole.This paper expands on the dynamic property of take-up in theory from the perspect of the whole system.In the meantime,it mainly studies dynamic analysis of take-up by finite element methord.By the optimization of the pull force in take-up,the whole system property is improved.And the system can work safly and reliably in various conditions.According to the dynamic analysis and optimization program which applys softwire Visual Basic 6.0 and Matlab 6.0,this paper also stimulates the whole process and the calculation results including force,displace are all shown with two-dimension and three-dimension graphics.
