Particle Dampers: Vibration Response Prediction
The particle damping technology is a passive vibration control technique. Particle dampers (PDs), as one of the passive damping devices, are widely used in aeronautical, mechanical, and civil engineering. They offer several advantages over viscous damping, for example structure simplicity, low cost, robust properties, and being effective over a wide range of frequencies.
This article presents a new simulation method based on multiphase flow theory (MFT) to evaluate the particle damping characteristics. The simulation method provides an effective instruction to the implementation of particle damping in practice. Compared to DEM, it offers the possibility of analyzing more complex particle damping systems with lower computational costs.
