查询词典 eddy current damping

It is worth to be noted that the needed driving current to the MR valve with both annular and radial damping gaps is less than that to the MR valve with annular damping gaps under the cut-off state of the MR valves, which show that the MR valve with both annular and radial damping gaps consumes less energy.

测试结果显示：（1）在相同的工作条件下，同时具有圆环和圆盘阻尼间隙的磁流变阀产生的压降更明显；（2）处于截止状态时，同时具有圆环和圆盘阻尼间隙的磁流变阀的激励电流明显小于具有圆环阻尼间隙的磁流变阀的激励电流，因此采用同时具有圆环和圆盘阻尼间隙的磁流变阀可以节约能量的消耗。
