Design requirements to magnetic bearings for primary circuit blowers of high-temperature reactors. Final report; Auslegungsanforderungen an Magnetlager fuer Primaerkuehlgasgeblaese von Hochtemperaturreaktoren. Schlussbericht

Abstract

To study the operational behaviour of blower shafts with magnetic bearings, a modular computer model was set up based on model laws, which permits to simulate shaft behaviour during dynamic loads acting on the blower shaft. During simulation runs, essential properties of position regulation (guide behaviour, secondary behaviour, and fault behaviour), and the behaviour of the blower shaft in the event of failure of a final stage of magnetic bearing electronics, with not-single-failure-proof and with failure-tolerant design of the final stages, as well as the effects of mechanical vibrations, e.g. as a result of earthquakes, on the behaviour of blower shafts were investigated. In order to transfer the results of the catch bearing tests to other designs of blowers with a vertical blower shaft, transmission laws and procedures were derived from theoretical considerations and from a dimension analysis which, however, could not be verified by means of tests. Application of the test results to horizontally placed blower shafts is possible only in part. The computer simulation model set up for the behaviour of the blower shafts is applicable without significant limitations to other blower shaft arrangements. (orig.).

[Deutsch] Zur Untersuchung des Betriebsverhaltens magnetisch gelagerter Geblaesewellen wurde anhand von Modellgesetzen ein modulares Rechenmodell aufgebaut, das die Simulation des Wellenverhaltens bei auf die Geblaesewelle wirkenden dynamischen Belastungen erlaubt. In Simulationslaeufen wurden wesentliche Eigenschaften der Lageregelung (Fuehrungsverhalten, Folgeverhalten und Stoerungsverhalten) und das Verhalten der Geblaesewellen bei Ausfall einer Endstufe der Magnetlagerelektronik bei nicht einzelfehlersicherer und bei fehlertoleranter Ausfuehrung der Endstufen sowie die Auswirkungen mechanischer Erschuetterungen z.B. infolge von Erdbeben auf das Verhalten der Geblaesewelle untersucht. Zur Uebertragung der Ergebnisse der Fanglagerversuche auf andere konstruktive Ausfuehrungen von Geblaesen mit vertikal gelagerter Geblaesewelle wurden Uebertragungsgesetze und Vorgehensweisen aus theoretischen Ueberlegungen sowie mittels einer Dimensionsanalyse abgeleitet, deren Verifizierung anhand von Versuchen aber nicht durchgefuehrt werden konnte. Die Uebertragung der Versuchsergebnisse auf horizontal gelagerte Geblaesewellen ist nur teilweise moeglich. Das aufgebaute rechnerische Simulationsmodell fuer das Verhalten der Geblaesewelle ist ohne gravierende Einschraenkungen auf andere konstruktive Anordnungen der Geblaesewelle uebertragbar. (orig.).}
