摘　　要：通过对某机车车钩及钩尾框进行疲劳强度计算,提出其疲劳寿命及破坏载荷(极限载荷),验证其是否符合设计指标,为以后车钩钩体及钩尾框的生产和研发提供必要的理论依据。By calculating the fatigue strength of the coupler body and coupler yoke for a locomotive, the fatigue life and failure load( limit load) are proposed to verify whether meet the design index,which provide the necessary theoretical basis for the future production,research and development of the coupler body and coupler yoke.

关 键 词：机车车钩 钩体 钩尾框 疲劳
