Abstract
Inerters are a class of vibration absorber which create a resistive force proportional to the relative acceleration across their two terminals. It has been previously shown that it is possible to create an inerter where the size of this force is variable, through use of a bypass channel controlled by a magnetorheological (MR) valve. However, the requirements and restrictions of such a device mean that existing design methodologies are insufficient. For example, as the pressure drop in the rest of the device is dependent on both the geometry of the device and the velocity of the fluid, it is important to design the valve with this in mind, in order to maximise the control range of the entire device, rather than just the valve itself. This work considers the effects of varying the dimensions of a valve and presents a performance metric to be used to allow comparison of different designs. The results are demonstrated as part of a model of a fluid inerter system.
