介绍了剪刀叉举升平台的研究现状,对双剪刀叉结构的油缸推力进行了理论推导,并进行了动力学仿真验证,确认理论计算式的正确性。与此同时,对举升平台双剪刀叉结构的强度进行了有限元分析,得到了底层剪刀叉铰点力与剪刀叉升角的关系,以及底层剪刀叉应力云图,并对结构的稳定性进行了校核,确认结构的强度和稳定性满足要求。

The research status of the scissor structure lifting platform was introduced.The thrust force of the cylinder in double scissor structure was theoretically derived,and the dynamic simulation and verification were carried out to confirm the correctness of the theoretical calculation formula.At the same time,the finite element analysis was carried out for the strength of the double scissor structure of the lifting platform to find the relationship between the force at the linkage point of the scissor structure at bottom layer and the leading angle of the scissor structure and get the stress cloud map of the scissor structure at bottom layer.The stability of the double scissor structure was checked to confirm that the strength and stability of the structure could meet the requirements.
