摘　　要：采用巴赫法对大型锻造操作机用倾斜缸缸底法兰的弯曲应力进行计算,并使用有限元法模拟各种因素对缸底法兰弯曲应力的影响,提出改善法兰受力状况的几项措施:增大翼缘的过渡圆角半径,对连接螺钉施加预紧力,在中心孔周边增加卸载槽。为同类设计提供参考。The bending stress of flange at the bottom of tilting cylinder applied to the heavy forging manipulator is calculated with Bach theory. The effects of various factors on bending stress of the bottm flange are simulated by use of finite element method （FEM）. Several solutions （ increasing the transition fillet radins of flange, inflieting the pretightening force on connecting bolt and adding a unload groove around the ceter hole） for im- proving the force starus of the flange are proposed, which could be reference for the same kind of design.
