This allows them toSiemens Digital Industries Software.perform vibrational and acoustic With Simcenter Testlab, we can intervene at any stage of the simulationWith Simcenter Testlab, wechain and find out how the change will be reflected in the basic design, says Otto Petraka. For example, when it can intervene at any stage ofcomes to the engines structure, when some of its parts create sound we can the simulation chain and find have a technical remedy. But if the problem arises from the electromagnetic design itself, we return out how the change will beto Drives Development department and optimize the basic design.
