摘要

以刮板输送机中部槽连接体系为研究对象,建立了中部槽连接体系不同姿态下的力学模型,并分别对推溜和拉架两种工况下中部槽连接体系的受力进行了分析研究。运用Ansys软件对其静态强度和疲劳寿命进行了仿真分析,结果表明中部槽连接体系最薄弱的地方发生在推移耳和哑铃窝处,是应力集中在哑铃窝处造成的,此结果与实际工作中凸端头的损坏相符,并提出了加大哑铃窝的圆角尺寸,以减小应力集中和降低应力峰值来解决此问题。研究为刮板输送机中部槽连接体系的设计提供了参考及理论基础。

Abstract

In this paper,the central groove scraper conveyor connecting system as the research object,the mechanics model of middle groove connection system different postures,and were to push the slide and Lycra two kinds of stress conditions in central groove connection system were analyzed. ANSYS software simulation analysis of its static strength and fatigue life,results showed that the central groove connection system weakest place in the passage of the ear and dumbbells fossa,fossa stress concentration dumbbell caused by this result and the actual work damage convex tip matches and proposed to increase the size of the dumbbell nest rounded to reduce stress concentration and reduce stress peaks to resolve this issue. The study was designed scraper conveyor system connecting central groove provides a reference and theoretical basis.
