摘要
提出了一种利用接触单元处理汽轮机中叶轮与轴的过盈配合问题,并运用有限元分析软件ANSYS进行分析,该方法为精确分析接触面间的过盈量及叶轮、轴的应力分布情况提供了有效手段。
By the contact elemen analysis the shrink fit in impeller with shaft of steam turbines, and the contact stress of shrunk-on disc have been investigated. By the ANSYS the finite element methods are used for calculating the deformation and contact stress of shrunk-on disc, the accurateness, effectiveness and reliability of new finiteel ement methods are described.
