Mechanical Mobility Relationship to the Dynamic Properties of the Structure-Borne Vibration Path within the Power Train and Vehicle 2003-01-1601

The structure-borne vibration paths within the power train and the vehicle are complicated and have been studied for years. This complication is a result of multiple attachment locations, and directions that exhibit flexural resonance in both the source-side and response-side of the path. To aid understanding in discussion of the dynamic properties of an individual vibration path, simplified mechanical mobility models are employed. These models are typically more simplified by assigning classical elemental properties to the individual components represented in the model. An analysis was performed to understand the significance of more “real-like” component mobility properties on system response and isolation, consistent with the conversational mathematical interpretation. Components within the vibration path are modeled as multiple lumped-parameter elements. Additionally, the discussion includes the mathematical derivation of the mobility properties of both the lumped parameter elements and combined system.
