磁流变弹性体阻尼器的设计及其磁路分析

The Design and Magnetic Circuit Analysis of Magnetorheological Elastomer Vibration Suppression Damper

高温合金叶轮是航空发动机的核心零件,但高温合金叶轮在加工过程中容易产生振动。因此针对加工高温合金叶轮过程中容易产生振动的情况,基于挤压工作模式,设计了一款磁流变弹性体振动抑制阻尼器。并对所设计的磁流变弹性体振动抑制阻尼器的整个磁路进行了计算和分析。分析结果表明,所设计的磁流变弹性体振动抑制阻尼器的间隙部分磁阻最大,而整个磁流变弹性体振动抑制阻尼器的磁路设计合理,磁场强度符合设计要求,且阻尼器具有较大的可调节范围。

High-temperature alloy impeller is the core parts of future high-performance aircraft engines.In allusion to vibration which is inclined to be generated in machining high temperature alloy impeller,it designed a magnetorheological elastomer vibration suppression damper based on extrusion mode.Then,the magnetic circuit calculation and analysis of magnetorheological elastomer vibration suppression damper that have been designed has be accomplished.The analysis show that reluctance value of gap part is maximum in this damper.And the design can meet the requirements.
