Relative movement analysis for a rapid and focused vibration analysis

Reino Eskelinen; Andreas Biemelt; Stephan Dr. Krämer

MBtech Powertrain GmbH, a company of the MBtech Group, has developed an efficient method called relative movement analysis (RMA) which is used in this example for optimization of the idling behavior and characteristics of a sedan with a V8 gasoline engine. This method enables engineers to rapidly and efficiently analyze the cause and effect chain, in this case, between the crankcase movements and steering wheel- and seat-vibrations. In the example presented, the RMA is utilized to optimize this vehicle’s engine mounting.

Relative Bewegungsanalyse zur schnellen und zielgerichteten Schwingungsanalyse

Reino Eskelinen; Andreas Biemelt; Stephan Dr. Krämer

Zur Optimierung von Leerlaufverhalten und -eigenschaften einer Limousine mit V8-Ottomotor entwickelte die MBtech Powertrain GmbH, ein Unternehmen der MBtech Group, mit der relativen Bewegungsanalyse (RBA) eine effektive Methodik. Damit gelingt es den Ingenieuren, die Ursachen- und Wirkungskette — im konkreten Fall zwischen Motorgehause, Lenkradbewegung und Sitzschwingungen — schnell und effizient zu analysieren. Im vorliegenden Beispiel wird die RBA zur Motorlager-Optimierung dieses Fahrzeugs eingesetzt.
