samcef 二维转子动力学超单元生成
二维转子动力学模型不仅可以用于系统的简化分析，也可以对其进行超单元生成，然后作为次级部件导入其他系统模型中。需要指出的是，超单元生成的计算，没有任何可以显示的三维结果。通过对本案例的介绍，可以了解到samcef在超单元生成方面的功能，主要包括：· Howto define 2D rotor geometry in Field (vertex, lines, face)· Howto define an elastic material· Howto create a superelement from this 2D geometry· Howto create a model, and import the superelement in it· Howdo define a Lumped mass attached to the superelement· Howdo define a Ground bearinglinked to retainednodes of the superelement· Howdo define locking on translational degrees of freedom of the superelement· Howto perform a “critical speed” analysis (ROTOR) of the model containing thesuperelement· Howto examine the results and report them. How to perform recovery ofthe superelement and see internal modal displacements相关操作视频见：Youku：http://v.youku.com/v_show/id_XODk4NjYzODA4.html百度：http://pan.baidu.com/s/1hqxOVJI
