Calculations in Automatic 3D Modeling of Turbine Stator Coil

Some calculations of automatic 3D parametric modeling are discussed in detail based on the forming principle, including coordinate transformation, parameters calculation, and derivations of the parametric representation of the equation of spatial curves. Especially, Various-gap modeling and transition part modeling are discussed. All these methods were verified by simulation of practical data and proved that the model can meet the requirement of production in some ways.
