摘　　要：探讨了电流变技术在汽车减振器上的应用.利用电流变流体的流变性能受电场影响的现象,研制开发了一种新型结构的减振器及其控制系统.试验结果表明:通过改变电流变流体的电场强度,从而改变其流动阻力,可以实现电流变减振器最佳阻尼力的控制以满足车辆安全性和舒适性的要求.This paper deals with the application of electro-rheological（ER） technology to au- tomobile shock absorber. According to the phenomenon of ER fluid influenced by electric field, a new kind of shock absorber and its control system are developed. Test results show that the flowing resistance of ER fluid can be changed by varying its electric field, and then the damping force of ER shock absorber could be best controlled to meet the needs of vehicle＇s safety and comfort performance.

关 键 词：电流变流体 电场强度 减振器 阻尼力
