颗粒阻尼器减震控制的数值模拟
Numerical Simulation of Vibration Control Effects of Particle Dampers
摘要
Abstract
Based on the discrete element method,a numerical simulation method for vibration control effects of particle dampers is established,and the way to determine the corresponding system parameters is introduced.A suitable particle damper system is modeled.On the basis of a reasonable time step and an efficient contact detection algorithm,the interaction between particles and the container is simulated.A shaking table test of a multi-storey frame with particle damper system is carried out.A comparative study show that the test results and the simulation results agree well with each other,which demonstrates that the proposed numerical simulation method can yield reasonabe control effect of particle dampers.关键词
