英文摘要：

A scissor mobile platform whose main function is to stand under load is designed and it＇s theory analysis is done according to the load conditions that platform may bear. The finite element analysis is done on the overall stiffness of the platform and stress near the hinge support, in order to increase the stiffness and reduce the stress, the structure shape of hollow rectangular cross section and structure near the hinge support is optimized, and satisfactory results are obtained. The research results show that the scissor mobile platform could meet the requirements of bearing load.
