Analysis And Study Of Bottom Correction Coils And Support Structure

Energy shortage problem is a critical issue to be addressed in today's society. And fusion energy is the hope of mankind to solve the energy crisis of future. ITER is to develop an experimental Tokamak fusion reactor which can be self-sustaining combustion, used to verify the engineering feasibility and reliability of thermonuclear fusion reactor, and to test the various elements required when the practical application of fusion energy.Bottom Correction Coils is an important component of the correction field system which in the ITER superconducting magnets. In this paper, major study the BCC coils and its supporting structure of the correction coils. First, the solid model is created by CATIA. Second, the magnetic-structural analysis of the coil is solved by finite element analysis software ANSYS. The results of the analysis also should be analyzed by stress Linearization. And thus the bottom coil must be assessed. In addition, improve the part of the coil, reduce the maximum stress of the coil suffered, and enhance the life of the coil. At last, modal analysis of the coil is conducted, natural frequency of the top 10 bands of the BCC coils is obtained, provide a reference for its design and manufacture.
