Optimization design of metal foam magnetorheological absorber
Abstract: Magnetorheological(MR) absorber is a new adjustable MR damper with MR fluid serving as carrying liquid, and because of its low power consumption, fast response, controllable, continuously adjustable damping force and so on, in recent years, (MR) absorber vibration has been widely used in control machinery, automotive and civil engineering and other fields. However, the conventional magnetorheological absorber is mainly used for low frequency, long trip, but for a slightly higher frequency of vibration damping efficiency is not satisfactory, mainly because of the smaller annular gap, magneto-rheological fluid from one chamber flowing to the other chamber takes a long time, so it is not suitable for high-frequency vibration control, and controllable conventional shock absorber damping is smaller, magnetorheological absorbers able to make for a slightly higher frequency and vibration control the damping force is larger, the hole can be taken to increase the number of the damping solution. Metal foam has some characteristics that it is porous and its voids is small, when the magneto-rheological fluid flow through the pores of the metal foam, a large damping force will be generated. In addition, tMetal foam has performance of cushioning and vibration absorption, combined with its magnetorheological fluid absorber will produce additional shock absorbing cushioning effect. Compared with conventional magnetorheological absorber, the kind of absorber with characteristics of low cost and long life. However, by theoretical calculations found that the damping force of this kind of absorber is lower.In order to improve the the performance of metal foam magnetorheological absorber, I will research this study to optimize the design.
