Abstract

Motor vehicles have an important role in our lives, the need for mobility making them present in daily activities. In a more open world, people want to be able to move, not only more and more, but also increasingly better. In the current context of the intensification, both nationally and internationally, of road transport, the need for safe traffic traffic is a primary objective for the operation of motor vehicles. Combining vehicle technology enhancements with an improved driver training, with a better road infrastructure design and an enforcement of existing traffic regulations is an important goal for society in order to increase road safety. During the operation of the vehicles, their component systems interact both with each other and with the external environment and these interactions are generating variations of some technical state parameters. As a result, there is a continuous change in the technical state of the vehicles, which causes variations in the dynamic, economical, air pollution, ergonomic, comfort and safety performances. This pape analyzes the vibrations of the steering system components, under different operating conditions and according to the technical state of the spherical joints. The measurements were made using a 4-channel digital recorder DA20-RION, with data processing software DA-20 VIEWER and a triaxial accelerometer Brüel & Kjær, type 4321. The paper highlights the possibility of monitorin the technical state of the spherical joints, analyzing the vibrations produced under different driving conditions of the vehicles and, at the same time, it opens the perspective of the implementation of intelligent devices to ensure the early detection of these failures.
