Suspension performance with one damper and one inerter

In Chen & Smith 2009, a class of realizations in which the number of dampers and inerters is restricted to one in each case, while allowing an arbitrary number of springs (which is the easiest element to realize practically), was considered and it was proven that at most four springs are needed—an explicit construction was given comprising five different circuit arrangements to cover all cases. This paper makes a comparative study of the performances of these five circuit arrangements when applied as mechanical suspension struts in a quarter-car model.
