“…Despite its simplicity, this model effectively captures the essential aspects of real-world vehicle dynamics and facilitates a fundamental comprehension of the limitations associated with suspension performance. Moreover, it serves as a foundational framework for suspension design that takes into account practical experience [1,2]. However, most quarter-car models used for studying vibrations assume tire-road contact [3].…”

The paper focuses on studying dynamic vibrations in a nondimensional field using a quarter-car model and governing equations. The analysis of vibrations is conducted in the frequency response domain considering both the no-contact and in-contact states. The study explores the limits of tire-road contact phenomena and identifies a series of separation points that form the separation boundary, which divides the plane into separation and contact zones. The study examines how suspension parameters influence the separation zone, aiming to offer valuable guidance to designers in making informed choices when selecting suspension parameters. The objective is to ensure the desired tire-road interaction, which ultimately improves vehicle dynamics and safety.

This paper conducts numerical simulations to delve into the phenomenon of tire-road separation using a half-car model. It scrutinizes scenarios where the tires lose contact with the surface, delving into the time response and phase portrait domains. This analysis captures vertical displacements and pitch dynamics in both in-contact and no-contact states. The research examines tire-road detachment for individual wheels and both wheels concurrently while also considering variations in road conditions and suspension structures. By comparing outcomes between scenarios where tires maintain contact and where they separate, the study offers valuable insights for vehicle designers, aiding them in selecting optimal suspension parameters to mitigate tire-road separation.
