摘要: 针对管道振动问题,提出一种适用于较大激励下内置栅格颗粒阻尼器,以改善传统颗粒阻尼器在较大激励时减振效果不佳的缺点。基于有限元法分析管道振动特性,其在风机可调转速区间存在第二、三阶固有模态频率,并应用多体动力学与离散元联合仿真模拟颗粒阻尼器对管道振动控制过程。通过搭建管道振动控制实验平台,其结果验证了仿真的可靠性。结果表明:颗粒直径为6 mm时内置栅格颗粒阻尼器减振效果较好;分别填充6 mm的不锈钢、氧化锆与铝合金颗粒时,发现填充不锈钢颗粒减振效果最好;颗粒填充率90%时,内置栅格颗粒阻尼器在管道二、三阶模态频率下分别减振53%、54%。对比分析内置栅格与无栅格颗粒阻尼器的耗能机理,发现内置栅格阻尼器中颗粒速度矢量更具规律性,且颗粒的动能、耗能量及其碰撞次数更多,验证了内置栅格颗粒阻尼器在较大激励时具有更优的减振效果。为排除阻尼器自身质量对减振效果影响,采取等质量对照以验证颗粒减振效果的有效性。

Abstract: To solve the problem of pipeline vibration, a kind of built-in grid particle damper is proposed to improve the traditional particle damper's poor damping effect under large excitation. The vibration characteristics of the pipeline are analyzed based on the finite element method. The second and third order natural modal frequencies exist in the adjustable speed range of the fan, and the control process of the pipeline vibration is simulated by multi-body dynamics and discrete element joint simulation. The reliability of the simulation results is verified by the experimental platform of pipeline vibration control. The results show that when the particle diameter is 6 mm, the built-in grid particle damper has better damping effect. When filled with 6 mm stainless steel, zirconia, and aluminum alloy particles respectively, stainless steel particles are found to exhibit the optimal damping effect. When the particle filling rate is 90%, the built-in grid particle damper can reduce the vibration of the pipeline at the second and third mode frequencies by 53% and 54%, respectively. The energy dissipation mechanism of the internal grid damper and the non-grid particle damper is compared. It is found that the particle velocity vector in the internal grid damper is more regular, and the kinetic energy, energy consumption and collision times of the particles are more frequent. It is verified that the internal grid particle damper has better damping effect at high excitation level. In order to exclude the influence of the mass of the damper itself on the vibration reduction effect, the equal mass control is adopted to verify the effectiveness of the particle vibration reduction effect.
