| 摘 要： | 颗粒阻尼技术中,颗粒与颗粒、颗粒与孔壁之间的碰撞和摩擦使得颗粒阻尼器具有高度非线性.为此,提出一种能够对颗粒阻尼器的减振性能进行快速预测的仿真算法——离散元-有限元耦合算法,并进行了试验验证,基于该算法研究了颗粒阻尼器的各参数对减振性能的影响规律.试验与仿真结果表明:耦合算法是有效的；影响颗粒阻尼器减振性能的主要参数是填充率和颗粒密度.

| Abstract: | The performance of particle damper is strongly nonlinear.The collisions and friction were existed between particles and particles,particles and cavity walls.A coupling simulation algorithm based on the combination of the discrete element method and the finite element method was presented to calculate the response of system with particle dampers.Comparison between the analytical and experimental results showed that simulation of the response of a cantilever plate with a particle damper was accurate.It showed... |
