The Mechanical Analysis of ELM Joint under Coupling Field

The Edge Localized Mode coil is the key component to prohibit phenomena of disruptive instability occur-ring in edge Tokamak plasma. And made Stainless Steel Jacketed Mineral Insulated Con-ductors. different pieces conductor are connected by joints. During normal operation device, joint will be shocked electromagnetic and thermal loads. Thus, it necessary perform mechanical analysis verify whether or not ELM has sufficient safety margin resist impact coupling field. In order obtain load boundary condition for analysis, launched first. Then temperature force density inserted into model. equivalent stress calculated. results indicate there intensity at supporting rail. To mitigate intensity, local structural optimi-zation design employed. Finally, evaluation carried out based on analytical design. assess-ment demonstrate optimized model withstand combined action multiple
