Abstract
In generally, a suspension system needs to be soft to insulate against road disturbances and hard to insulate against load disturbances. It cannot achieve with a traditional passive suspension that only considered to the stiffness and damper. On other hands, the formula cars need high tire grip on racing challenge by reducing rolling displacement at corner or double change lands with the simplest suspension dynamics system. In this study, the paper clarifies some issues related to suspension system with inerter to reduce displacement and rolling angle under impact from road disturbance on Formula SAE Car. In this paper, we integrate some kinds of suspension system with inerter on quarter-car and half-car models. We propose some new designs, which have some advantages for suspension system by improving dynamics. We optimize design of model based on the minimization of cost functions for roll dynamics, by reducing the displacement transfer and the energy consumed by the inerter. The base model is a passive suspension model then we carried out quarter-car and half-car model with different parameters; they show the benefit of the inerter in proposal suspension system. The advantage of research is integration a new mechanism, the inerter; this system can improve the vehicle oscillation.
