“Verification and manufacturability of robust mass damping (RMD)”

Dynamical performance of undamped tuned mass dampers (TMD) is sensitive to mistuning, both in forcing frequency and natural frequency. This design of a robust mass damper (RMD) can handle a large range of operational excitation and complex damping due to variation in visco-elastic material, geometry and temperature. Excitation originates from a high-acceleration stage and resonance in leaf spring guiding. Manufacturing challenges were to integrate the RMD in the leafsprings robustly, e.g. operator independent assembly, and to keep to simple geometry to allow standard moulds for the viscoelastic. We will discuss both the design process and experimental results.

The speakers will be: Reinout Veldhuizen en Ivan van der Kroon

We will start at 12:02pm on January 17 2022
