Introducing a Round-Robin Challenge to Quantify Model Form Uncertainty in Passive and Active Vibration Isolation

The aim is to quantify model form uncertainty in a passive and active vibration isolation system example during a round-robin challenge among IMAC’s Model Validation and Uncertainty Quantification (MVUQ) technical division. In this context, passive means that the vibration isolation only depends on preset inertia, damping, and stiffness properties. Active means that additional controlled forces enhance the vibration isolation. The focus is on studying multiple mathematical models of the same one-mass oscillator system to predict its structural dynamic behavior against a consistent set of experimental data to ensure direct comparability. The models differ in their scope and complexity; the experimental data will be offered to different research groups that are yet to be constituted during this IMAC. The participants are welcome to join the research group and discuss their results in an exclusive IMAC session reserved for round-robin results in the following years.
