Study on Parametric Design of ITER Cryostat Based on CATIA

Cryostat is an important equipment of International Thermonuclear Experimental Reactor (ITER).It is the outer part of ITER Tokamak. There are three issues to solve the parametric design of cryostat: First, the parametric description of cryostat model; Second, program design; Third, the establishment of Database. In this paper, take a simplified model of the cryostat as an example, after the parametric description of cryostat finished, the parametric design of cryostat has realized through ACCESS Database and the automation technology of the secondary development of CATIA under VB (Visual Basic).
