MR Damper Characterization - Lehigh - Damper 1

MR Damper Characterization tests conducted in Lehigh aims to identify MR Damper No. 1 which will be used in Real-Time Hybrid Tests(RTHT).

The characterization process is based on five trials. These are(change this info):
1) Active Motion Control(AMC) Identification
2) Reaction against Constant Current/Random Displacement
3) Reaction against Random Current/Random Displacement
4) Response Time of MR Damper with Various Input
5) Reaction against Sine Wave with Active Motion Control(AMC)
6) Reaction against Sine Wave with DC Power Supply
7) Rise Time of MR Damper Force
8) Settling Time of MR Damper Force
9) Rise Time with Various Input Currents

The results have been used to generate an adequate model to explain the behavior of the MR Damper.

MR damper used in the characterization tests has the following properties:
The length of the stroke is 1.5m.
The available stroke length is ±279mm.
The electromagnetic coil consists of 368 turns of 18 AWG magnet wire with an annular gap of 1.0 mm between the piston head and the inside diameter of the damper cylinder.
The damper is filled with approximately 19 liters of MRF-132DG type MR fluid.
Damper is manufactured by Lord Corporation.

在里海大学开展的磁流变阻尼器（MR Damper）特性测试旨在对1号磁流变阻尼器进行标定，该阻尼器将用于实时混合试验（Real-Time Hybrid Tests, RTHT）。

特性标定过程基于五项试验，具体如下（信息调整）：
1) 主动运动控制（Active Motion Control, AMC）识别
2) 恒定电流/随机位移下的响应特性
3) 随机电流/随机位移下的响应特性
4) 磁流变阻尼器在多种输入下的响应时间
5) 主动运动控制（AMC）下正弦波激励的响应特性
6) 直流电源供电下正弦波激励的响应特性
7) 磁流变阻尼器力的上升时间
8) 磁流变阻尼器力的稳定时间
9) 多种输入电流下的上升时间

测试结果已用于构建能够充分描述磁流变阻尼器行为的模型。
