Power Line Corona Rings Optimization

Innovative silicon insulators for high power transmission lines have been designed with ANSYS. Our customer wanted to design insulators with lower electrical fields than usually available in the market by optimizing the geometrical shape of the conducting corona rings. The entire design and optimization process was done in ANSYS Workbench by means of a thermal-electric analogy, while a parametric model was used for the geometric optimization. The customer could benefit from an automated workflow in ANSYS Workbench and know-how transfer for the optimization process. A new product line with significant competitive advantage was designed.

FE Analysis of a grinding machine

The development of new functionalities of existing machine platforms, as well as the conception of innovative machine-tools can be accelerated by reducing the number of prototypes required prior to the final series release to the market. The mechanical behavior of a grinding machine depends to a great extent on the vibration behavior of single components, selected assemblies and the entire machine. The presence of critical eigenfrequencies and modes inside the rotational speed range of the spindle must be avoided to guarantee the precision of the treatment.
