摘要

磁流变液被广泛地应用在汽车减震器、表面抛光和其他精加工处理中。讨论基于铝的磁流变液在磁场、不同的负载和振荡频率条件下的摩擦特性。在有、无磁场下对磁流变液基于铝的往返式摩擦特性进行评估。在不同荷载和振荡条件下分析实验条件与运动周期的关系。通过测量表面粗糙度和观察表面图像比较样品表面，并评估了磁流变液基于铝的往复摩擦特性。%Reciprocating friction characteristics of magneto-rheological (MR) fluid for aluminum under a magnetic field at different loads and oscillation frequencies were studied when MR fluids were worked in reciprocating motions such as in dampers for automobiles, and surface polishing and other finishing. Thus, experiments were carried out to evaluate the reciprocating friction characteristic of MR fluid for aluminum. The obtained data from the tests are sorted in groups depending on various loads and oscillation frequencies, to analyze the relationship between test condition and travel cycle. Surfaces of specimens were compared by measuring the surface roughness and observing the surface images. The performance of reciprocating friction characteristics of MR fluid for aluminum is evaluated through analyzing the experiment results.
