The HL-2M tokamak was constructed at Southwestern Institute of Physics. The support system is one of the main subsystems of the device. The magnetic coils and vacuum vessel are located and integrated by the support system. According to its function, the support system is divided into gravity support, support for poloidal field coils, and anti-torque structure for toroidal field coils. The structure design and the finite element analysis of the support system is introduced in this paper.
