Abstract:

On the basis of the physics experiment requirements of EAST, the ion cyclotron range of frequency (ICRF) antenna has been designed with the capacity of moving back and forth along the rail in the radial direction of EAST by the hydraulic drive. With the aim of demonstrating the feasibility of the movable structure, the analysis has been carried out for the support components of the ICRF antenna movable structure by applying the formulas and the finite element method, analysis results satisfy the design requirements. In addition, the mechanical analysis have been performed for the ICRF antenna, and the engineering commissioning have been done for the assembled ICRF antenna movable structure, results of mechanical analysis are shown that the ICRF antenna can move stably as well as results of commissioning meet what was expected.
