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.

“…Neglecting the consideration of tire-road separation can lead to inadequate dynamic response predictions [4]. Therefore, it is necessary to reassess vibration responses by incorporating a switching differential equation system [5]. In this study, the vehicle is simulated in both contact and no-contact states.…”

“…In the paper, the nonlinear characteristics of elastic elements and damping elements in the suspension, the deformation of the frame, and the contact deformation of the tire and the road surface are fully considered, and a rigid-flexible coupled vehicle dynamics model is established using the ADAMS/ VIEW platform. 13,14 In this paper, according to the tire transfer function and the acceleration signal on the axle, the road displacement excitation is calculated, which is used as the input of the dynamic simulation.…”

The human body is extremely sensitive to roll vibration, which is also an important indicator for evaluating vehicle comfort. In order to improve the ability of anti-roll vibration of vehicles, the methods of mathematical modeling, dynamic simulation, and vibration test are used in this paper. The generation mechanism, dynamic change law, and key influencing factors of the roll vibration are analyzed. The analysis results include: the dynamic simulation results are in good agreement with the test results, and the use of the simulation model is beneficial to the analysis and control of the roll vibration; the roll vibration is caused by the relative dynamic deformation of the left and right suspensions, and the larger the relative deformation, the more obvious the roll vibration; the optimization of the position and damping of the shock absorber is conducive to the control of roll vibration, which greatly improves the comfort of the vehicle. The research results provide theoretical basis and reference for grasping the characteristics of the roll vibration and vibration reduction design.

“…Controlling the excitation like road surfaces and driving conditions in a stable environment combined with equipment to measure sound and vibrations are factors that make such study possible. Approach that utilizes both vibrational and acoustic responses of a car was extensively studied [2][3][4]. This paper presents the approach to study mentioned effect by using a unique brand new test stand located in Acoustic Research and Innovation Center (ARIC) by KFB Acoustics in Poland.…”
