ITER真空绝热冷质支撑性能测试平台设计与研究

真空绝热冷质支撑（cold mass support，CMS）是国际热核聚变反应堆（International Thermonuclear Fusion Reactor，ITER）中的关键支撑部件之一。为了检测已制造完成的冷质支撑的性能是否达到合格验收标准，在交付前需对它进行摩擦性能测试和机械强度测试。通过分析复杂工况下冷质支撑的受载特点，结合摩擦测试标准ASTM D1894-14和摩擦力的工程计算结果，设计了冷质支撑摩擦性能测试平台。基于冷质支撑的受载工况，先初步设计了冷质支撑机械强度测试平台，并通过弯矩梁的受力分析确定了10号工字钢为弯矩梁的最佳材料，再利用液压伺服装置对冷质支撑施加工况载荷，完成了冷质支撑机械强度测试平台相关设备和工装的结构设计。考虑到单独实施摩擦性能测试和机械强度测试的各项成本，结合2项测试的特点，设计了冷质支撑性能一体化测试平台。结果表明冷质支撑性能一体化测试平台能够有效缩短测试周期和降低检测成本，可为冷质支撑的工程质量认证及后续批量生产提供保障。

Design and research of ITER vacuum insulation cold mass support performance test platform

Vacuum insulation cold mass support(CMS)is one of the key supporting components in the International Thermonuclear Fusion Reactor(ITER).In order to detect whether the performance of the manufactured CMS meets the acceptance criteria,it is necessary to conduct a friction performance test and a mechanical strength test before delivery.By analyzing the loading characteristics of the CMS under the complex working conditions,combining the friction test standard ASTM D1894-14 and the engineering calculation results of friction force,a CMS friction performance test platform was designed.Based on the loading conditions of CMS,a CMS mechanical strength test platform was initially designed,and the 10 I-beam was selected as the best meterial for the moment beam through the force analysis of the moment beam.Then,the hydraulic servo device was used to apply working load to the CMS,and the structural design of the equipment and tools related to the mechanical strength test platform was completed.Considering the individual costs of friction performance test and mechanical strength test,a CMS performance integrated test platform was designed through combining with the features of two tests.The results indicate that the CMS performance integrated test platform can shorten the test cycle and reduce the test cost,which provides guarantee for the engineering quality certification and subsequent mass production of CMS.
