摘要
针对某型号发动机,基于低频大刚度大阻尼的理想悬置特性要求,提出了一种新型流动模式磁流变悬置,采用ANSYS对磁流变悬置的核心结构进行磁场有限元分析,确保磁路设计的合理性。为研究流动模式磁流变悬置在低频大振幅激振时的动态特性,建立了磁流变悬置的集总参数模型,利用MATLAB分析许用激励电流范围内的动态特性,克服以往仅对几个离散激励电流点的动刚度及阻尼滞后角进行分析的不足,为磁流变悬置的智能隔振控制奠定了基础,具有重要的工程应用价值。
Aim to a type engine, a novel flow mode Magneto -Rheological （MR） engine mount is design base on ideal dynamical performance of engine mount. Magnetic circuit is checked by ANSYS finite element method, which assured the reasonable of design. In order to research the dynam- ical performance of flow mode engine mount during large amplitude in low frequency, lumped parame- ter model is established, and the dynamical performance is analyzed during exciting current permit range by MATLAB, which overcome drawbacks of conventional dynamical performance research among several discrete exciting current. Those provide a solid foundation for engine vibration isolation control intelligently, which has important value during the application of MR engine mount.
