| 1 | 多级蜿蜒磁路式磁流变阻尼器的设计与分析显示文摘为了改善磁流变阻尼器的阻尼特性,设计了一种多级蜿蜒磁路式磁流变阻尼器。该磁流变阻尼器通过导磁环和阻磁环的堆叠来引导磁感线的走向,迫使磁感线数次穿过磁流变阻尼器的节流通道,提高了节流通道的利用效率。建立了考虑磁流变液非线性流动特性的数学模型,并通过有限元方法进行了磁路分析,进而对所设计的磁流变阻尼器的特性进行预测。将所设计的磁流变阻尼器的阻尼特性与具有相同体积的传统磁流变阻尼器进行了比较,包括可控阻尼力、等效阻尼和动态范围。结果显示在正弦激励速度为0.125m/s,并通入2.0A电流的情形下,所设计的磁流变阻尼器的最大可控阻尼力为11 000N,约为传统磁流变阻尼器的2.3倍。此外,所设计的磁流变阻尼器并没有使零场情形下的阻尼力增大。所设计的磁流变阻尼器具有优良的阻尼性能,适用于广泛的工程减振应用。 | 程明 陈照波 KIM Kyongsol 焦映厚 | 2017 | 工程设计学报2017，24，3： | 7 |
| 2 | A Novel Shear Mode MR Damper and Its Mechanical Performance显示文摘This paper presents a linear shear mod magneto-rheological(MR) damper which can be applied to vibration control system.The proposed MR damper featured by a small amount of MR fluid,absence of a gas chamber or diaphragm and piston with helix slotted.Because of the absence of a gas chamber or diaphragm,unnecessary damping force caused by gas compression is not generated.Magnitude and damping coefficient of damping force are two important indexes to evaluate performance of MR damper.The piston with helix slotted is developed based on mechanical analysis on rheological characteristics of MR damper,and the damping performance of MR damper with helix slotted piston is investigated through performance experiments and comparison with analytical simulation.The results indicate that helix slot may increase friction coefficient on surface of the piston,and improve the maximum damping force without reducing damping coefficient of the damper.The reflux of MR fluid may be increased by adjusting helix angle suitably,which avoids the settlement of MR fluid. | Kyongsol Kim Zhaobo Chen Yang Zhang Inchol Kim | 2017 | Journal of Harbin Institute of Technology(New Series)2017，24，3： | 1 |
