【摘要】 基于Pro/Engineer建立了机座的三维实体模型,应用ANSYS软件,用有限元方法进行了产品的模态分析和瞬态分析,得到了振动频率、主振型、工作过程中的应力、应变等参数,以及产品的主要破坏形式和危险位置,分析结果表明现有电机的结构满足设计要求,同时给出了机座结构的优化方案,为同类产品的开发和改进提供了参考依据。更多还原

【Abstract】 The 3D-solid model of the YKSL400-6 cryopump motor was built up.A finite element model and transient analysis was completed.Pro/Engineer and ANSYS were applied to the analysis of the motor.The natural vibration frequencies and its corresponding stress,strain,displacment were obtained.The result proved that the actual structure was reasonable.It can provide the information for improving the motor.更多还原
