Analysis of a Semi-Active Suspension Model with an Attached Inerter Device

Resumo

This study employs computational numerical analysis to investigate a semi-active suspension system
featuring an integrated inerter device within a 1/4 vehicle model. The study aims to assess suspension performance
and the impact of the inerter on vehicle dynamics. Semi-active suspension offers adaptable parameter adjustments
based on current conditions. Incorporating an inerter in suspension, a recent focus, adds inertia without increasing
mass. A quarter car vehicle model was employed for analysis, representing vertical dynamics and passenger
comfort. Numerical simulations encompassed a step road profile, comparing semi-active suspension versus passive
suspension. Results, including body displacement, highlighted improved performance with the inerter. Vertical
displacement and accelerations were significantly reduced, enhancing comfort. This underscores the inerter's
potential to enhance semi-active suspension performance effectively.
