“…Therefore, numerical modelling of VV-SPs' system and simulations on the influence of SPs on the dynamical response are of great importance for the Tokamak design. Many research works have been done for the design of the Notes: I P , plasma current; R, major radius; a, minor radius; A, aspect ratio; k , elongation; d , triangularity; and B t , toroidal field Tokamak structural components by using commercial software such as the ANSYS and Opera-3d (Guirao et al, 2012;Kotulski et al, 2008;Liu et al, 2010;Rozov et al, 2012). Some of these works indicated that the EM-mechanical coupling effect may affect the dynamical response of the Tokamak structure.…”

Purpose In this paper, numerical modelling and dynamical response analysis were performed for the HL-2M vacuum vessel (VV) and shielding plates (SPs) during a plasma disruption by using an updated ANSYS parametric design language (APDL) code developed by the authors. The purpose of this paper is to investigate the influence of the SPs on the dynamical response of VV owing to a transient electromagnetic (EM) force and to optimize the design of SPs in view of the minimization of the structural dynamic response. Design/methodology/approach The Lagrangian approach, i.e. the moving coordinate scheme developed by the authors, was updated to tackle the EM-mechanical coupling effect in the dynamic response analysis of the VV-SPs system due to the transient EM force during plasma disruptions. To optimize the structural design of HL-2M SPs, the influence of the key parameters of SPs, i.e., the side length, thickness and material properties, was clarified on the basis of the numerical results and an optimized design of SPs was obtained. Findings The updated APDL code of the Lagrangian approach is efficient for the transient dynamical response analysis of the VV-SPs system owing to the EM force. The SP of a smaller side length, larger thickness tungsten material better mitigates the dynamical response of the VV-SPs system. Originality/value The Lagrangian approach was updated for the EM–mechanical coupling dynamical response analysis of the VV-SPs system, and the influence of the SP parameters on the dynamical response of the VV-SPs system of HL-2M Tokamak was clarified.
