摘　　要：为研究磁性阻尼动力吸振器在管道减振方面的应用,根据定点理论开发设计了一款适用于三维管路的单向有阻尼动力吸振器,并基于visual basic编制了关键参数计算器。通过有限元仿真计算、安装位置参数优化和试验验证等方法,验证了该动力吸振器在三维管路减振中的有效性。得出如下结论:使用该套动力吸振器的设计方法开发的动力吸振器,可以有效降低三维管路的振动。试验验证的减振效果与仿真计算验证的减振效果相近。In order to solve the problem of pipeline vibration in power industries such as nuclear powers and thermal powers,a one-way damped dynamic vibration absorber suitable for three-dimensional pipelines based on fixed point theory was developed and designed.And a key parameter calculator based on visual basic was compiled.The effectiveness of the dynamic vibration absorber in three-dimensional pipeline vibration reduction was verified through finite element simulation,installation location parameter optimization,and experimental verification.Results show that the dynamic vibration absorber developed can effectively reduce the vibration of three-dimensional pipelines.The vibration reduction effect verified by experiment is similar to that verified by simulation calculation.
