Mechanical Engineering
Digital balancing based on three-dimensional surface measurement

The present invention is a novel method for balancing rotating machine parts by means of digital balancing based on three-dimensional surface measurement. The method presented does not involve physical balancing of the machine part in a test rig provided for this purpose. Instead, the required mass balance is predicted by means of suitable simulations, which are based on a detailed geometric image of the real rotor. Based on the simulation results, mass balancing takes place in order to minimize the determined unbalance as far as possible.

Lightweight construction
Lightweight element/semi-finished product made of two or more joined structured sheets or combination of structured and smooth sheets

The invention relates to an area-expanded lightweight element/semi-finished product which consists of at least two layers of sheet metal and at least one structured sheet metal. Characteristic of the structured sheet metal are inserted macro-stiffening elements which do not have any larger planar sections and correspond to a honeycomb shape. The individual sheets are arranged on top of each other and are joined by joining. In addition to straight components, curved components can also be produced.
