Vibration Analysis of Two-dof Systems
The vibration analysis oftwo-dof systems bears many common features with that of n-dof systems, yet it also bears simplifying features that make it amenable to longhand calculations. Moreover, as we show here, two-dof systems can be analyzed completely with graphical methods. We show that the Mohr circle, a rather fundamental tool in engineering analysis, finds extensive applications in understanding the behavior of the kind of systems at hand. Once the analysis oftwo-dof systems has been fully understood, that of n-dof systems comes virtually as a byproduct.
