摘要
采用有限元软件对刮板输送机中部槽中板受力进行分析,发现中板中部及两侧均出现不同程度应力集中情况,增大中板磨损从而降低使用寿命。基于此,对中部槽结构进行优化,在中板上布置凹坑降低中板应力集中程度,后通过模拟对比有限凹坑规格及布置参数,最终确定凹坑直径、深度分别为2 mm、7 mm,凹坑间距、排距均为50 mm。将优化方案应用到SGZ1000×3×1000中部槽上后,按照磨损报废表明确定中部槽运输量可达到2 000万t,优化前中部槽运输量为1 500万t,所提中部槽结构优化方案取得较好成果。
The stress concentration in the middle and both sides of the middle plate of the scraper conveyor was found to be different by using finite element software to analyze the stress on the middle plate of the scraper conveyor.Therefore,the structure of the central trough was optimized by arranging pits on the middle plate to reduce the stress concentration of the middle plate,and then by simulating and comparing the finite pit specifications and layout parameters,the diameter and depth of the pits were finally determined to be 2 mm and 7 mm respectively,and the pitch and row distance of the pits were 50 mm.after applying the optimized scheme to the SGZ1000×3×1000 central trough,it was determined that the central trough could The transportation capacity can reach 20 million t,compared with 15 million t before the optimization,which shows that the proposed optimization scheme of central chute structure has achieved good results.
