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 bearing linked 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
