摘　　要：某钢厂转炉采用三点支撑自调螺栓连接装置,为分析3种工况下自调螺栓的应力分布,本文采用有限元法进行分析,首先建立托圈及自调螺栓整体模型,施加预紧力及相应边界条件,从而得到自调螺栓的应力分布.结果表明,倾动角度为0°时,自调螺栓承受最大应力193.2 MPa,满足实际使用要求,但对于螺栓应做倒圆角处理,减少应力集中.Three-point support self-adjusting bolt connection devices are adopted by a steel plant.In order to analyze the stress distribution of the self-adjusting bolt under three working conditions,the finite element method is applied,in which the force and corresponding boundary conditions are given to obtain the stress distribution of self-adjusting bolts.The results show that when the tilt angle is 0°,the self-adjusting bolts bear a maximum stress of 193.2 MPa,which meets the actual use requirements,but the bolts should be rounded to reduce stress concentration.
