【摘要】 采用有限元方法模拟矿用THIELE重载圆环链受纯拉伸负荷时三维接触的VonMises等效应力分布和拉伸方向上的正应力分布,从力学理论上解释并探讨了圆环链间弹性接触对其发生断链破坏的影响。更多还原

【Abstract】 A three-dimensional finite element analysis of contact between round link chains for mine use is presented for tension of the test load. Results for the Von Mises equivalent stress fields and normal stress fields of the chains are given for a perfectly elastic hypothesis. The significance of the contact stress for crack initiation in the stress concentration zone is interpreted and discussed theoretically.更多还原
