A non-obstructive particle damping model of DEM
Source abstract
Abstract
The non-obstructive particle damping technology has been used successfully in many fields for vibration reduction. However, it is difficult to predict the damping characteristics due to complex collisions in the dense particle flow. The discrete element method makes it possible to consider effects of granularity such as the particle size, number of particles and friction between two particles. The validity of this numerical method is examined by a comparison of the experimental results. The discrete element method simulation system is further examined with examples for its computational complexity and effectiveness for different density parameters. It is shown that the mass ratio and material density influence the damping performance.
