高性能机器常常工作在高转速下,产生较大的动静载荷并严重影响轴承。液膜轴承在设备的可靠性及轴承转子系统振动及性能方面起着重大的作用。为保证轴承系统的可靠运转,其设计不仅需要基于液体动压轴承本身的模拟,还需要建立在特定转子轴承系统的转子动力学分析结果基础上,因为轴承特性对转子的振动响应会带来显著的影响。

SoftInWay,叶轮机械领域领先的方案提供者,在蒸汽、燃气轮机、轴流/径流式压缩机、涡轮增压器、水泵、发电机及发动机等的不同转子轴承系统设计和分析方面积累了丰富的经验,并在此基础上开发了一套软件工具用于转子轴承系统设计、转子动力学分析以及轴承模拟,来帮助转子轴承的设计及分析工作者们。

在本次在线研讨会中,将会介绍液体动压轴承的优化方法。这一方法包含整个转子-轴承系统的多学科模拟。这些模拟包含轴承液力特性计算和优化并引入转子-轴承系统的转子动力学分析作为优化的约束条件。这一工作展示了不同的参数例如轴承间隙、长度等如何影响诸如轴承最小油膜厚度、摩擦力及转子轴承系统临界速度等关键性能指标。这一方法被用来考虑功率损失和转子动力学限制的情况下为一个大功率感应电机优化轴颈轴承。优化过程使用了AxSTREAM ION模块因而更强大,而转子-轴承系统是利用AxSTREAM Rotor Dynamics模块和AxSTREAM Bearing模块来进行模拟。

主要内容:

  • 转子-轴承系统的设计及分析简介
  • 液压动力轴承优化方法综述
  • 13.5 MW感应电机的液体动压轴承优化的算例分析
  • 现场展示AxSTREAM Rotor Dynamics模块和AxSTREAM Bearing模块的特征与功能。

面向人群:

  • 有兴趣从事设备转子动力学及轴承计算优化的旋转机械设备工程师及设计师
  • 有兴趣通过轴承优化提高设备寿命及性能的工程师
  • 有兴趣在未来从事叶轮机械设计优化的工程系学生
