【摘要】 回旋加速器广泛地应用于国防基础科学研究和国民经济建设中。将虚拟样机技术应用到回旋加速器的设计,施工建造等方面,有助于降低制造成本和工程风险。论文以CYCIAE-100的主磁铁结构为研究对象,利用有限元软件COSMOSWorks平台,进行了静态分析和接触计算,根据计算结果分析了磁铁结构的机械性能,并对部分零件进行了优化分析。论文在详细调研加速器结构分析的现状,以及存在问题的基础上,对主磁铁的具体结构形式和受力特点进行了理论分析,经过合理简化,确定了分析的模型结构和载荷边界条件。在主磁铁结构分析过程中,采用了SolidWorks建立其三维参数化装配体模型,用接触条件、摩擦系数和螺栓接头等来模拟各个零件间的相互作用,避免了零件间作用力的计算和繁琐的人工处理过程。对盖板方案——整体盖板和分块盖板结构建模分析,比较了两种方案。并且分析了分块盖板结构在不同工作状态下的结构变形和强度。磁铁中采用翅膀连接方式来连接磁极和盖板。通过研究分析翅膀的形状参数以及翅膀上螺栓的位置分布对整体结构的刚度和强度,局部变形的影响,为翅膀结构的优化设计提供了参考方向。更多还原

【Abstract】 Nowadays cyclotrons are widely used in fundamental researches in national defense and economic development. It will apparently reduce the cost and risks of the project by applying the VP (Virtual Prototyping) technique in the design and construct of the cyclotrons. Static analysis and contact calculations for the main magnet of the CYCIAE-100 were researched using Finite Element Analysis (FEA) software COSMOSWorks in this dissertation. Based on these computations, the mechanical property was analyzed, and optimizations of some parts were considered.First of all, the frame and the load of the magnet are studied in details based on the research of the structural analysis. Then the analysis model, the forces and boundary conditions of the magnet are determined.The three dimensional parametric assembled model was built using SolidWorks. In this model, the contact sets, the friction coefficient and the bolt connectors were used to simulate the interaction among the parts. This greatly reduces the calculations and the manual processing.The design of the lip: the one-part lip and the two-part lip, are compared. And the deformation and strength of the magnet under different work conditions are analyzed.The connection of the pole and lip uses a wing-shape structure. The influence of the shape and bolts of the wing on the whole stiffness and strength of the magnet is analyzed, which will bring forward some optimization.更多还原
