The Optimal Design of Magnetroheological Oscillating Platform

The design process of a set of magnetorheological oscillating platform was presented which is made up of controllable oscillating producing device, signal collecting device, computer software for dynamic analysis, magnetorheological damper etc. The working and configuration principles of the platform were introduced,relationships was discussed between some structure parameters, for example the damping slot and piston diameter,mechanism performances like damping force and dynamic range.A model was put forward for magnetorheological damper optimizing design which is based on multi- targets layout principle.Considering the damping force and dynamic range, the model can satisfy demands of diverse applications for designing damper with good performances by assuming proportional values and minor targets.
