摘　　要：文中通过理论计算选取处于设计临界点的2种结构类型万向环,并利用有限元对选取样本进行受力分析。通过对2种类型万向环的质量、加工难度、运输难度等方面的分析得出结论:方形万向环在受力能力及成本控制方面比圆形万向环有较大优势。在铰链型膨胀节设计中,应优先选择方形万向环作为设计方案。This paper selects two structure types of gimbal ring at critical point through theoretical calculation, and analysizes the force of the samples by using finite element method. Finally make a conclusion through the analysis of the two types of gimbal ring weight, processing difficulty, transportation difficulty, compared to circular gimbal ring, square gimbal ring has the advantage in terms of the stress capability and cost control. The scheme of the square gimbal ring design should be selected first in the de- sign of gimbal expansion joint.
