    • Disclosed is a method and electromagnetic device for manufacturing an anisotropic magneto-rheological elastomer (MRE) with an improved magneto-rheological effect. The electromagnetic device includes upper and lower electromagnets, and a test piece located therebetween. The upper and lower electromagnets are configured to apply a magnetic field of variable strength, which may be controlled by current applied from a power controller, to the test piece in a desired direction or orientation. More specifically, the device is designed in such a manner that carbonyl iron powder (CIP) (magnetic-responsive particles) dispersed in a magneto-rheological elastomer using natural rubber as a matrix can be oriented in the application direction of the magnetic field. A MRE produced by the method and electromagnetic device of the invention prevents formation of bubbles within a test piece, thereby improving the arrangement/orientation of CIP with the matrix.
    • 公开了用于制造具有改进的磁流变效应的各向异性磁流变弹性体(MRE)的方法和电磁装置。 电磁装置包括上下电磁体和位于它们之间的试片。 上电磁铁和下电磁铁被配置为施加可变强度的磁场,其可以通过从功率控制器施加的电流以期望的方向或取向施加到测试片。 更具体地说,以使用天然橡胶作为基质分散在磁流变弹性体中的羰基铁粉(CIP)(磁响应粒子)可以在磁场的施加方向上取向的方式设计。 通过本发明的方法和电磁装置产生的MRE防止在试件内形成气泡,从而改善了CIP与基质的排列/取向。
