多极板电流变阀应用于避震器之研究

以流动模式（flow mode)多极板之电流变阀（electrorheological valve)进行避震器阻尼力特性的研究。由于电极板的大小直接影响到流体流动的剪力及避雷器的阻尼力，因此使用多极板型式来探讨避震器的特性。设计有1－5个流道之并联及1－3个流道之串联多极板电流变阀的电流变避震器，并使用自制的电流变液进行实验。由研究结果显示，流动式并联极板之电流变避震器，一个流道之阻尼力最大，流道极板增加则阻尼力反而下降，而流动式串联多极板之电流变避震器之阻尼力则随极板数递增，故需要高阻尼力之避震器较适合使用串联多极板型式。

Study on the Shock Absorber Using Multielectrode Electro-Rheological Valve

This paper studies the generation of damping forces of shock absorbers using the multielectrode electrorheological valve (ER valve) of flow mode. Due to the fact that the size of electrode affects the magnitude of damping force, we design two shock absorbers using the multielectrode ER valves to study the effect of multielectrode arrangement. One of the absorber utilizes one to five electrode gaps of parallel arrangement, while the other has one to three electrode gaps of serial arrangement. The silicone oil-based ER fluid is prepared in our lab for the experiments. The results from theoretical and experimental studies show that the damping force generated using the one electrode gap is the maximum among the multielectrode of parallel arrangement. The resultant damping force is larger as the number of gaps is increased for the serial arrangement of the multielectrode. Thus, we conclude that the serial arrangement of multielectrode is more suitable for shock absorbers which require high damping force output.
