The superconducting dipole prototype magnet of the collector ring for the Facility for Antiproton and Ion Research (FAIR) is an international cooperation project.The collaborative simulation and testing of the developed prototype magnet is presented in this paper.To evaluate the mechanical strength of the coil case during quench,a 3-dimensional (3D) electromagnetic (EM) model was developed based on the solid97 magnetic vector element in the ANSYS commercial software,which includes the air region,coil and yoke.EM analysis was carried out with a peak operating current at 278 A.Then,the solid97 element was transferred into the solid185 element,the coupled analysis was switched from electromagnetic to structural,and the finite element model for the coil case and glass-fiber reinforced composite (G10) spacers was established by the ANSYS Parametric Design Language based on the 3D model from the CATIA V5 software.However,to simulate the friction characteristics inside the coil case,the conta173 surface-to-surface contact element was established.The results for the coil case and G10 spacers show that they are safe and have sufficient strength,on the basis of testing in discharge and quench scenarios. 相似文献

EAST核聚变实验装置是国家“九五”大科学工程项目,是一个具有非园截面的全超导托卡马克装置,本文主要说明真空室内部部件安装基准与真空室本体相连的过渡件——基准环的设计,及其在HALO电流所产生的电磁力等作用下的结构分析。真空室内部部件是安装在基准环上的EAST装置主机的重要部件之一,由于直接面对高温等离子体,它们的安装基准即基准环的精度将是非常关键的。基于此分析基准环在环境变化时产生的变形量大小,验证基准环的强度等能否满足要求。介绍变形及装配等带来的不满足精度要求将带来的后果。在后续的实验中成功验证基准环的设计,获得稳态的、极长的长脉冲等离子体,并实现全电流下的双零高β和单零高等离子体的运行实验。 相似文献

机械设备磨损状态的评价参数具有多元化、阶段性及动态性的特点,决策往往取决于技术人员的经验。通过油液监测判断机械设备健康状态时,参数多难以凭主观选择,以致磨损状态的准确界定一直是瓶颈。为此,以风电齿轮箱为对象,研究其颗粒信息、污染度及油品信息对磨损状态的影响,在根据磨粒种类的危害程度初步量化磨损度的基础上,对监测数据降噪后,通过支持向量机获取指标的显著性系数,进而算得参数权重,确定的关键参数为磨损颗粒数量、铁磁性颗粒质量分数、平均颗粒尺寸,简化了磨损度的指标,能提高风电齿轮箱的故障诊断效率。 相似文献
