【摘要】：為了得到一種板式電渦流阻尼器的阻尼特性,文章建立了板式電渦流阻尼器的有限元模型;對不同氣隙條件下的阻尼系數(shù)和導(dǎo)體板表面的最大磁感應(yīng)強度進行了分析計算;并在自主開發(fā)的振動測試裝置上測試了板式電渦流阻尼器的阻尼特性。研究結(jié)果表明:有限元計算結(jié)果與試驗結(jié)果吻合較好,根據(jù)有限元模擬和振動測試試驗可以準(zhǔn)確設(shè)計和評價板式電渦流阻尼器的阻尼特性。
[Abstract]:In order to obtain the damping characteristics of a plate eddy current damper, the finite element model of the plate eddy current damper is established, and the damping coefficient and the maximum magnetic induction intensity on the surface of the conductor plate under different air gap conditions are analyzed and calculated. The damping characteristics of the plate eddy current damper are tested on the self-developed vibration test device. The results show that the finite element calculation results are in good agreement with the experimental results. The damping characteristics of plate eddy current dampers can be accurately designed and evaluated by finite element simulation and vibration test.
