Abstract: Inerters have become a hot topic in recent years especially in
vehicle, train, building suspension systems, etc. Eight different layouts of
suspensions were analyzed with a quarter-car model in this paper. Dimensionless
root mean square (RMS) responses of the sprung mass vertical acceleration, the
suspension travel, and the tire deflection are derived which were used to
evaluate the performance of the quarter-car model. The behaviour of semi-active
suspensions with inerters using Groundhook, Skyhook, and Hybrid control has
been evaluated and compared to the performance of passive suspensions with
inerters. Sensitivity analysis was applied to the development of a high
performance semi-active suspension with an inerter. Numerical simulations
indicate that a semi-active suspension with an inerter has much better
performance than the passive suspension with an inerter, especially with the
Hybrid control method, which has the best compromise between comfort and road
holding quality.
