本文介绍一种新型振动控制元件──电流变体阻尼器。该阻尼器基于小孔节流原理，利用具有固液两相特性的新型材料──电流变体研制而成，其输出力矩大小可由电信号直接控制，响应迅速。作者在文中对阻尼器的结构原理、理论模型以及性能测试情况进行了介绍。 This article describes a new type of vibration control element ─ ─ current variable damper. The damper based on the principle of small orifice throttling, the use of a new material with solid-liquid two-phase characteristics ─ ─ current variants developed, the output torque can be directly controlled by the electrical signal, fast response. The author introduces the structural principle, theoretical model and performance test of damper in this paper.
