Die Magnetisierungskurven und Ummagnetisierungsverluste weichmagnetischer Werkstoffe zeigen sich stark abhängig von den zur Bearbeitung eingesetzten Trennverfahren. Nach dem theoretischen Ergründen der Ursachen und dem Entwurf einer genauen und praxistauglichen Prüfmethodik erfolgt die messtechnische Charakterisierung dieser Abhängigkeiten an ausgewählten Werkstoffen, Trennverfahren, Probengeometrien und Magnetisierungsbedingungen. Dies ermöglicht erste Rückschlüsse auf die Sensitivität magnetischer Eigenschaften gegenüber Bearbeitungseffekten. Anhand der Ergebnisse können schließlich Modelle zur Beschreibung der Materialdegeneration an Bearbeitungskanten identifiziert werden. Weiterführend werden drei Methoden zur Nachrechnung von Magnetkreisen eingeführt, um im Entwurfsprozess elektrischer Maschinen den Einfluss von degenerierten Eigenschaften abzuschätzen. Diese werden abschließend an praktisch relevanten Anordnungen mit konventionellen Berechnungen und Messwerten verglichen. / Magnetization curves and core losses of soft magnetic materials are strongly dependent on the applied cutting processes. After identifying the theoretical causes and designing an accurate and convenient measuring technique those dependencies are determined from selected materials, cutting processes, sample geometries and magnetization conditions. Thus, first conclusions about the sensitivity of magnetic properties to cutting effects are possible. The results eventually enable the identification of models specifying the material degeneration at cutting edges. Furthermore, three methods are introduced in order to describe magnetic circuits, as common in electrical machines, but under the influence of degenerated properties. Finally, those methods are compared to conventional calculations and measurements at practically relevant cores.

In dieser Arbeit wurde ein computergestütztes, dynamisches Ein-Spur-Modell eines Pkw mit einem parallelen hybrid-elektrischen Antrieb (P2-Topologie) in Matlab-Simulink entwickelt. Es erlaubt die Skalierung des elektrischen Leistungsanteils und simuliert die Betriebsarten elekt- risches, konventionelles und hybrides Fahren, Bremsenergierückgewinnung und Start-Stopp- Betrieb. Ferner kann durch die Modellierung einer Einscheiben-Trockenkupplung zwischen Verbrennungs- und Elektromotor die Momentenübertragung bei schlupfender Kupplung wäh- rend des Anfahrens oder beim Start des Verbrennungsmotors durch den Elektromotor nach- gebildet werden. Die Fahrzeugsimulation kann in drei verschiedenen Fahrzyklen (NEFZ, WLTP, FTP-75) durchgeführt werden. Als Ausgabegrößen stehen u.a. der Kraftstoffverbrauch, die CO2-Emissionen, die Antriebs- und Rekuperationsarbeit am Verbrennungs- bzw. Elektro- motor und an den Rädern sowie die dafür benötigte bzw. rückgeführte elektrische Energie zur Verfügung. Zusätzlich kann der zeitliche Verlauf zahlreicher relevanter Größen dargestellt wer- den. Die Validierung der Simulation zeigte eine gute Übereinstimmung mit den Daten eines realen Fahrzeuges in Bezug auf Beschleunigungsverhalten, Maximalgeschwindigkeit und Kraftstoffverbrauch. / In the frame of this Master Thesis a dynamic single-track-model of a hybrid electric vehicle was developed. The model comprises basic operation modes such as electric, conventional and hybrid driving, recuperation of braking energy and engine start-stop. It allows to scale the split of the propulsion between the combustion and electric engine. A further fundamental com- ponent is the model of a friction disc clutch, enabling the simulation of torque transmission of a slipping clutch during the vehicle start and the upspeeding of the combustion engine through the electric engine. The program offers three driving cycles for simulation (NEDC, WLTC, FTP- 75). Fuel consumption, CO2-emissions, propulsion and recuperation work of the combustion engine, electric engine and the wheels are provided as output variables as well as the required and recuperated electric energy. Furthermore several relevant variables are displayed in their progress over time. The model was validated against real vehicle data showing a good corre- lation regarding acceleration, maximum speed and fuel consumption.
