磁流变阻尼器结构设计及其阻尼特性试验研究
|
摘要
目前市场上的磁流变阻尼器由于阻尼力与体积过大而并不适用于滚筒洗衣机安装与控制,依据滚筒洗衣机悬挂系统阻尼器力学性能以及磁流变液的材料特性和磁路设计原则,设计并制作了一个单出杆的剪切阀式磁流变阻尼器样品,采用Instron 8800材料试验机对所设计的磁流变阻尼器进行特性试验,采集其在不同电流、频率和位移下的阻尼力。采用MATLAB对实验数据进行处理,分析磁流变阻尼器的阻尼性能,结果表明该磁流变阻尼器设计是符合设计要求,可用于滚筒洗衣机抑振控制策略的研究。
Magnetorheological damper on the market at present is not applied to install and control drum washing machine because the damping force and the volume are too large. Based on mechanical properties of suspension damper and material characteristics of the magnetorheological fluid and magnetic circuit design principle,a single lever shear valve type of magnetorheological damper was designed and produced. Using Instron 8800 materials testing machine could collect the data of damping force under different current,frequency and displacement. Analysis of the mechanical properties on the data showed that magnetorheological damper could meet design requirements,it could be used for the suppression control strategy research of drum washing machine vibration.
