Inerter potential for vehicle vertical dynamics

Current vehicle suspension is designed to improve simple, but contradicting main criteria: Comfort level of passengers of load defined by their vibration exposition especially at higher frequencies and maximized and even tyre contact force, which effects braking distance, manoeuvrability, but also pavement damage. In addition, it is also desirable to minimise roll, pitch under braking, acceleration and cornering (handling). Design of automotive suspension was driven to its limits with passive traditional components like springs, dampers and tyres. Semi-Active damping with controlled damper characteristics has been successfully used to decrease both road tyre dynamic force and braking distance ([2] ), but still increases vehicle design complexity. Active damping may improve vehicle behaviour using smart control algorithms, but it is so energy costly that it is not broadly used. Further improvement of vehicle suspension behaviour according to contradicting criteria can be achieved by introduction of additional components. In this paper, potential of novel element, inerter is investigated, including design feasibility.
