ITER纵场磁体支撑原型件三维加载测试平台设计

摘要

根据ITER运行的主要危险工况,设计了一个专用的三维加载测试平台,并对该测试平台进行了结构有限元分析.有限元分析结果表明,三维测试平台结构有足够的强度和刚度,能满足磁体支撑原型件的三维加载测试的精度要求,可以用该设计方案进行制造.为了确信三维加载测试的可靠,制定了专门的三维加载测试平台的验收方案并按此方案对测试平台进行了可靠性测试.%In order to gain the high reliability of the gravity support (GS), the three-dimensional mechanical loading test of GS, used for stimulating ITER operation load cases, should be performed using GS prototype. To carry out this test, a special test platform for GS prototype is designed based on the dangerous ITER operation load cases, and finite element analysis (FEM) of this platform is conducted. FEM analysis shows that the intensity and stiffness of the test platform are sufficed, and that it can meet the accuracy requirements of the three-dimensional loading test for GS prototype. An acceptable criterion for this platform is designed, and the reliability of the platform is testified by this criterion.
