We offer an internship / a thesis on the subject of “Program module rotor dynamics lateral” to promote technical support.
FIMA manufactures turbo machinery for the chemical industry. Our centrifugal compressors generate high pressure differences and need relative high speeds to achieve this; operation is usually run above the first bend-critical speed. As a special machinery builder with a typical batch size of one, a rotor-dynamic pre-calculation of the lateral oscillations needs to be performed for every piece of machinery.
The calculation must take gryoscopic effects into account as they exercise a major influence on standard rotors. The influence of rigidity and damping of the bearing, usually a friction bearing, must also be taken into account.
Particularly in the case of these applications “squeeze oil dampers” are now used. They are designed with an thin encapsulated oil film that surrounds the bearing. The result is typically high damping values and very soft bearing supports so that even anti-friction bearings can be run in the critical speed range.
Take the opportunity to get to know a medium-sized company that gives you an insight into the workings of a global player in fluid mechanics.
