Abstract

The present invention relates to a parametric modeling method applicable to the coil at the end of the stator winding of a generator, characterized in that the steps are as follows: Step 1, inputting the geometric parameters of the coil; Step 2, defining the cross-sectional shape of the coil; Step 3, Modeling of the geometric model of the end coil; step 4, establishing a finite element model of the coil. The invention has the advantages of parametrizing the modeling of the end coils of the stator winding and simultaneously establishing the finite element model of the end coils so as to be applied to the research on the vibration characteristics of the stator winding end structures.

Description

technical field [0001] The invention relates to a parametric modeling method for the end coil of the stator winding of a generator, which is suitable for various types of units whose end coils are involute expansion forms, and belongs to the calculation and improvement of the dynamic characteristics of the end structure of the stator winding of the generator technology field. Background technique [0002] The end coil of the stator winding plays an important role in outputting the induced current to the grid in the generator. Its vibration has always been the main concern in the research and development of generators. Since the end coils of the stator winding adopt the involute expansion method, it is difficult to establish a reasonable finite element model of the end coils. [0003] In the past, the modeling method of the end coil is to use the three-dimensional design software to build the model. The operation process is relatively complicated, and it is not easy to modi...
