摘要
设计并搭建一套磁流变液阻尼器力学性能测试系统,用该测试系统对所制作的磁流变阻尼器的力学性能进行实验研究。利用LabVIEW编写数据采集平台对温度和压力传感器的电压信号进行采集,并利用MATLAB对数据进行分析。探究磁流变液阻尼器在不同温度下施加不同电流时的阻尼力特性,并初步探讨磁流变液的黏温性能。实验结果表明:磁流变液阻尼器输出阻尼力在20~40℃之间受温度的影响较大,且随着温度的升高,阻尼力呈下降趋势。
A set of mechanics performance test system for magnetorheological fluid damper was built and debugged. LabVIEW was used to compile a data acquisition platform to collect the voltage signals of temperature and pressure sensors, and the data were analyzed by using MATLAB. The damping force of the magnetorheological fluid damper under different temperatures applying different current was tested and the damping force decreasing with the temperature rising were discussed. The result indicates that the temperature has a great influence on the magnetorheological fluid damper at the temperature range of 20~40 ℃ and the damping force decreases with the increase of temperature.
