Abstract:  During the HL-2M tokamak installation plan formulation period and the project construction 
process, CAD&CAE design analysis method was adopted to optimize the assembly plan for many times according 
to the requirements of system function and installation schedule. The position relationship between each system 
was checked and the installation scheme was simulated by computer. Finally, a complete and implementable 
installation process and technical scheme were formed. The assembly plan was analyzed and studied 
comprehensively, and the construction of the three-dimensional datum network, the measurement of key 
components, the insulation and cushion process plan, and the magnetic permeability control of the key 
components of device are summarized and discussed in this work, to provide valuable design and assembly 
reference for the construction and development of the fusion reactor in the future.
