Comparison of Characteristics of the Components Used in Mechanical and Non-Conventional Automotive Suspensions

Abstract

The paper presents the comparison of the characteristics of spring and damping components used in conventional and non-conventional automotive suspensions. The conventional suspension is based on steel coil springs and hydraulic dampers with fixed characteristics. As an example, the adaptive non-conventional suspension shows the characteristics of hydropneumatic suspension components (suspension are constantly being developed and is now based on mechatronic control systems of damping characteristics). The paper summarizes the advantages and disadvantages of these solutions.

Modern suspension systems for automotive vehicles and their test methods

“…The development of methods is directed at obtaining additional diagnostic information (not only the vibration amplitude in the resonance), such as, for example, the phase angle and the unambiguous association of this information with the vehicle mass distribution (the ratio of sprung and unsprung masses) [6,[14][15][16][17][18][19][20][21].…”

Analysis of Structural and Material Aspects of Selected Elements of a Hydropneumatic Suspension System in a Passenger Car

“…With regard to the hydropneumatic strut, it is the indicator diagram that determines overall forces of restitution and resistance in the function of displacement [23,24,26]. Curves of loading and relieving show dissimilar courses, thus creating a hysteresis loop in the diagram.…”

Underwater robotic system for reservoir maintenance

“…Other problems, like negative influence of ROV self-noise on detection aspect in water environment [21] or ROV control [22][23][24][25] will be considered as well.…”
