摘要
用有限元法分析计算了扁挤压筒内套850 mm×250 mm在其外边缘加不同的分布力时其应力分布情况,并分析计算了不同扁挤压筒结构的应力,得到如下结论:在内比压为520MPa时,其内套外边缘采用部分紧配合,可使扁挤压筒的受力显著改善,降低应力集中处最大应力值,从而大大提高扁挤压筒寿命。
By means of finite element method,the stress distribution of the outside edge of the 850mm×250mm inner sleeve of flat extruded cylinder when the edge is given different distributed force and the stress of different flat extruded cylinder structure are analyzed and calculated.The conclusion is come to that when the internal specific pressure is 520 MPa.the tight fit of outside edge of inner sleeve is partly applied,which can remarkably improve the stress of the flat extruded cylinder,reduce the maximum stress where the stress is centralized located,enhance the service life of the flat extruded cylinder.
