Abstract:
This paper mainly carries out a combined theoretical and experimental research of the property of ER damper as bumper in large force impact. Experiments show that the ER damper has little effect in large force impact using current ERF, and theoretical analysis also prove the conclusion. The main reasons and the further measures in order to improve the situation are discussed in detail.
Key words:  ER fluid, ER damper, Impact resistance

电流变阻尼器的抗冲击性能研究
靳争团,高跃飞,任建亭,姜节胜
摘要:
从理论和试验两个方面研究了所设计的电流变阻尼器在大冲击下的抗冲击性能,分析了电流变液性能与阻尼器结构参数对抗冲击性能的影响.认为采用高性能的电流变液体及改变结构参数,都可以使电流变阻尼器的高速缓冲性能提高.电流变液流速对电流变液的屈服应力影响显著,其值随流速的增加按指数规律减小.从定性、定量两个方面分析了电流变阻尼器作为阻尼器效果不明显的原因为:由电流变效应引起的阻尼力在整个液压阻力中所占比例太小,不能通过改变电压来使液压阻力具有很大的调节可控范围.
