| Abstract: | Bridge is an important part of the bridge crane, which is used to support the mechanical and electrical equipments of the whole crane machine and the heavy objects. The strength and stiffness are important factors of bridge crane design and manufacturing. The stiffness and strength of the crane structure is analyzed by the theoretical calculation method and the finite element simulation method on Marc. The extreme worse condition of the bridge structure is analyzed and simulated, and the load bearing and stress distribution are obtained. And then the bridge structures strength and stiffness are checked. The foundation study results provide effective theoretical support for the security and reliability of bridge crane structure which is in service. |
