摘要：箭体吊具是一种常见的火箭地面设备，其结构主要由横梁组件、吊耳、连接耳、弓形卸扣、轴销、钢丝绳、叉架等组成。箭体吊具起吊时需要承受产品的重力、自身重量及起吊过程纵向过载等载荷。为了保证箭体起吊过程安全，需要对吊具结构进行强度校核分析。使用Hypermesh软件建立吊具主框架结构有限元模型，并进行强度计算分析，得出了吊具主框架结构的应力和变形云图，结果表明，吊具主框架结构刚度较好，可满足使用要求。

Abstract：The lifting-device is a kind of familiar ground support equipments for Rocket body, whose structure is made up of horizontal beam module, lifting ear, connecting ear, bow shackle, axis pill, tightwire, and so on. The lifting-device bear gravity of Rocket body, oneself weight and vertical overload during rinsing to hang. In order to guarantee safe for process of rising to hang, strength analysis is necessary for the lifting-device. Use the Hypermesh software to set up a finite-element-analysis mold for the lifting-device, and strength analysis is carried on, the result of stress and stiffness is calculated. The results express rigidity of the lifting-device is enough, can satisfy to the usage requirements.
Key words：lifting-device；rocket body；finite element analysis；Hypermesh
