摘要
液压管路在外界激励、流体脉动和水锤的作用下容易发生多维度振动,影响输送效率,导致事故发生.设计了一种新型的半主动磁流变阻尼管夹,以期对液压管路的低频振动进行控制.首先,为了研究该装置的力学性能,建立了减振系统的动力学模型.然后,采用PID控制方法进行数值仿真,证明了PID控制算法的有效性和稳定性;最后,进行了不同频率和幅值下的表征试验.结果表明,本文提出的磁流变阻尼管夹在激励频率1～10 Hz范围内,能有效抑制液压管路的轴向位移和加速度.该研究为液压管路的低频振动控制提供了新的技术途径.
Abstract
Hydraulic pipelines are prone to multidimensional vibrations under the influence of external excita-tions,fluid pulsations,and water hammer effects,which can affect transportation efficiency and lead to accidents.Accordingly,this paper designsa novel semi-active magnetorheological(MR)damper clamp structure to control the low-frequency vibrations of hydraulic pipelines.Firstly,to study the mechanical performance of the device,a dynamic model of the vibration isolation system was established.Then,numerical simulations were conducted u-sing the PID control method,demonstrating the effectiveness and stability of the PID control algorithm.Finally,characteristic experiments were carried out under different frequencies and amplitudes.The results show that the proposed magnetorheological damper clamp can effectively suppress the axial displacement and acceleration of hy-draulic pipelines within the excitation frequency range of 1 Hz to 10 Hz.This study provides a new technical ap-proach for the low-frequency vibration control of hydraulic pipelines.
