颗粒阻尼器的DEM仿真与实验研究

his paper is about one kind of cylinder particle damper. On one hand, the particle damper is simulated by Visual Basic through DEM modeling method and calculational theory; On the other hand, an experiment is designed in order to verify the simulation results. After finishing all the work we find that: First, the simulation results are much close to the measured experimental results, which indicates that the simulation procedure is reasonable; second, the dissipated energy has a property of increasing with the acceleration amplitude and decreasing with the excitation frequency.
