Abstract
The study of vibratory systems in the current context of Automotive Engineering brought with it a series of technological innovations. The development of highly safe, comfortable and dynamically efficient vehicles is only one of the benefits of vibration theory in the progress of the automobile industry, especially in the design of vehicle suspensions. The automotive suspensions are responsible for absorbing irregularities from the ground providing comfort as well as maintaining the stability of the vehicle. The aim of this paper is to construct an experimentalof a reduced ¼ vehicle suspension model, in which simulations of a suspension system characteristic of popular cars can be performed. The system consists of four parts: the sprung mass (relative to ¼ of the weight of the car), the unsprung mass (corresponding to the tire wheel assembly), the springs and dampers belonging to the suspension assembly and tire characteristics. The analysis was performed using the MATLAB R2015a software, considering a scale of 1:10 between the experimental bench model and the suspension of a passenger car. The vertical responses of the sprung mass to the excitations of a terrain profile are evaluated, showing the high sensibility of this system. With the experience it is possible to still use the device as an efficient teaching tool in the study of vibrations and vehicular dynamics.
