对造纸机石辊三种不同设计方案,用有限元方法计算出石辊的应力分布,并按照几种强度理论讨论其破坏的可能性。由此确定了最佳设计方案,还对提高紧固螺母强度提出了建议。
Three different design schemes of the paper machine stone roller were used to calculate the stress distribution of the stone roller by the finite element method and discuss the possibility of destruction according to several strength theories. This determines the best design, but also to improve the strength of the fastening nut made recommendations.
