This paper presents a comparative analysis of eight distinct passive ISD (Inerter-Spring-Damper) suspension configurations, systematically investigating the impact of inertance on vehicle dynamic performance. Using a quarter-car model and time-domain simulations, the responses were evaluated in terms of maximum displacement and RMS acceleration of the sprung mass, aiming to balance comfort and stability. The parametric analysis revealed significant variations between topologies, with three configurations demonstrating superior performance. The obtained results provide practical guidelines for ISD topology selection in automotive design and contribute to understanding the inerter’s role in enhancing passive suspension systems.
