摘　　要：为解决离心水泵管道的振动问题,采用有限元法对管道进行流体动力学分析,确定阻尼器安装位置。基于离散元法,建立颗粒阻尼器仿真模型,研究颗粒在不同粒径和填充率下阻尼器能耗的变化规律,确定最佳颗粒参数。根据颗粒阻尼耗能机理,对阻尼器腔室数量和形状进行优化,以改善颗粒运动状态。仿真结果表明:当阻尼器内部填充95%的5 mm颗粒时,耗能最佳。大密度波纹五腔颗粒阻尼器可以显著提高颗粒运动速度,增强颗粒间以及颗粒与阻尼器壁面间的摩擦和碰撞程度。与传统颗粒阻尼器相比,耗能效果更加显著。搭建水泵管道减振试验台,通过实验验证模拟结果的准确性,可为颗粒阻尼器在实际工程中的应用提供参考。In order to solve the vibration problem of the centrifugal pump pipelines,the finite element method was used to conduct fluid dynamics analysis of the pipeline and determine the installation position of the damper.Based on the discrete element method,a particle damper simulation model was established to study the changes of energy consumption of the damper under different particle sizes and filling rates,and the optimal particle parameters were determined.Based on the energy dissipation mechanism of particle damping,the number and shape of damper chambers were optimized to improve the particle motion state.The simulation results show that when 95%of 5mm particles are filled inside the damper,the energy consumption is optimal.The high-density corrugated particle damper with five cavities can significantly raise the particle motion speed,enhance the friction and collision effect between particles and between particles and the damper wall.Compared with traditional particle dampers,the energy dissipation effect of this damper is more significant.Finally,a vibration reduction test bench for water pump pipelines was built,and the accuracy of simulation results were verified through experiments.This work has provided a reference for the application of particle dampers in practical engineering.
