Coupling Analysis on Hydrauic Press and Forming Moulds of the Containment of Nuclear Power Reactor

Abstract:

Based on actual production, the each mould in the production line of containment of nuclear power reactor and the frame of THP22-4000 hydraulic press was modeled by coupling method. By using the finite element analysis simulation software ANSYS Workbench, the stiffness and strength of each coupling models were analyzed by node-coupling method. According to the results having been analyzed formerly, the distribution of stress and strain of each coupling models were studied, and the influence rules of assembly area of mould on workbench and close-height of mould on coupling stiffness were drawn, so as to guide the mold and the hydraulic structure design and optimization. Under the prerequisite of ensuring the forming precision of containment, it would be possible to configure and optimize scientifically and rationally the structure of forming molds and equipments, lower the costs of productions, and obtain higher economic benefits.
