| 中文摘要: |
| 现有的管路振动主动控制器设计中，大多以较简单的二自由度简化模型为基础，只考虑了刚体位移，而忽略了管路结构变
形对振动的影响。课题组提出一种考虑管路结构变形的主动控制策略，以连续梁模型为基础建立复杂管路系统模型，将系统动力方程经模态变换到广义坐标下，
针对广义坐标设计主动控制器，最终达到减小管路各个部位各个方向上振动的效果。使用MATLAB Simulink进行仿真计算，结果显示该主动控制器能较好地减小管
路系统振动。 |
| 英文摘要: |
| Most of the existing design of active pipe system vibration controllers are based on a two DOFs simplified model, which only considers the
displacement of rigid body but neglects the impact of pipeline structural deformation. An active control strategy considering the structural deformation of pipe system was introduced. Based
on the continuous beam model, a complex pipeline system model was established to transform the system dynamic equations to generalized coordinates. An active controller especially for
generalized coordinates was designed, and reducing vibration of each part of pipe system in different directions was achieved. MATLAB Simulink simulation results show that the active
control system has excellent vibration reduction effects. |
