In this article,a kind of hydraulic clamping device for solidified barrel of nuclear waste is introduced. The threedimensional model of the hydraulic clamping device for the solidified barrel of nuclear waste is established by using the SolidWorks. The stress and strain diagram of the hydraulic clamping device for the solidified barrel of nuclear waste under rated load is obtained by the statics analysis based on the Workbench Ansys software. The feasibility and safety of the structure design are verified,which provides a reference for design of the clamping d...
