摘　　要：以惯性通道-解耦膜-振荡线圈作动器式主动液阻悬置为研究对象,探讨中高频动特性的简洁有效表达方式及其参数识别方法,便于主动控制的应用。基于作动器动子固有频率远高于惯性通道固有频率、惯性通道在中高频段因流体阻力增加而关闭的内在特征,忽略惯性通道自由度,建立单自由度的集总参数模型,得到振荡线圈式主动液阻悬置主动特性与被动特性的简洁表达式,明确被动特性具有3个水平段与主动特性具有2个水平段的形态特征,并进行了试验验证。基于高频弹性特性测试系统,配合适当夹具系统,探讨一种免于单独开发高频试验台的动特性测试方案,可获得高达400 Hz有效的主动与被动特性。Active hydraulic mount with an inertia track,decoupling membrane and oscillating coil actuator is taken as a research object,this paper focuses on the concise and effective expressing for the mid-highfrequency dynamic characteristics and corresponding parameters identification method. Based on the intrinsic properties that the natural frequency of the actuator mover is much higher than the one of the inertia track,and the fluid channel is closed due to the increase of fluid resistance in the mid-high-frequency bands,the degree of freedom(DOF)for the fluid channel is ignored,and a 1-DOF lumped parameter model is established. The concise expressions of the active and passive dynamic characteristics are obtained for the active hydraulic mount with oscillating coil actuator. It is revealed that the passive dynamics have three horizontal sections and the active dynamics have two horizontal sections,and these conclusions have been validated by experiments. Based on a high-frequency elastomer test system,combined with an appropriate clamping,a dynamic test scheme is provided,which avoids the development of a highfrequency test bench,and which can be used to obtain effective active and passive characteristics up to 400Hz.
