惯性器是一类减振器，它产生与两端的相对加速度成比例的阻力。先前已经表明，通过使用由磁流变 (MR) 阀控制的旁路通道，可以创建一个力大小可变的惰性气体。然而，这种设备的要求和限制意味着现有的设计方法是不够的。例如，由于设备其余部分的压降取决于设备的几何形状和流体的速度，因此在设计阀门时必须考虑到这一点，以便最大化整个设备（而不仅仅是阀门本身）的控制范围。这项工作考虑了改变阀门尺寸的影响，并提出了一个性能指标，用于比较不同的设计。结果作为流体惰性系统模型的一部分进行了演示。
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.
