中文摘要：

设计出一种多腔体串联结构的电流变阀，该阀设有若干个带有集散式轴流孔的平行电极，腔体高度和数量可调，从而可满足较大范围的调速要求。推导了电流变阀压差公式，明确了压差与场强、流量和腔体高度的关系。利用Fluent软件仿真分析了电流变阀的流体压力分布情况和流动情况。设计制作了电流变阀的系列样机，进行了验证试验和对比试验。结果表明：圆板式电流变阀腔体高度在1 mm以下性能较好；串联结构能有效提高电流变阀对压差和流量的连续调节能力。

英文摘要：

A kind of multi-chamber cascaded electrorheological valve was proposed.Some parallel plate electrodes with distributing axial-flow holes were set in it.The valve could meet requirement of wide range speed regulation because its flow gap and number were adj ustable conviniently.The fomula of pressure difference was deduced,so the inherent laws among pressure difference,field intensity, flow rate and chamber height were discovered.The fluid pressure distribution and flow condition in the valve were simulated by using Fluent software.At last,the validation and contrast tests were made on series prototype electrorheological valves.The results show that the disc-type valve runs well while the height of chamber is within 1＆#183;0 mm.Cascaded structure is also proved helpful to improve the per-formance of electrorheological valve.
