dc.description.abstract	This paper presents the findings of an empirical analysis of a roll-plane Hydraulically Interconnected Suspension (HIS) system under vehicle articulation mode excitation. The articulation mode of a four-wheel vehicle describes the in-phase motion of two diagonal opposed wheels, with adjacent wheels moving out of phase. This mode is critical for better off-road vehicle handling, particularly in utility vehicles; nonetheless, only little research has been conducted addressing this issue. Although a soft articulation mode is desired for enhanced road-holding, the widely used anti-roll bars, necessary for increased roll stiffness, also make the articulation mode stiffer. As a result, one or more wheels may lose ground contact on uneven surfaces, compromising vehicle stability and safety. Roll-plane HIS systems are capable of decoupling vehicle roll from articulation at full-car level; thus HIS systems are attracting ongoing attention from researchers. A comparative experimental study of HIS and anti-roll bars has been carried out on a purpose-built four-post dynamic suspension test rig in order to evaluate vehicle dynamic performance in both roll and articulation modes. For this the vehicle is tested at two different configurations: conventional suspension and roll-plane HIS. Consequently, it has been demonstrated that the HIS system offers a significantly softer articulation mode compared to conventional anti-roll bars, improving vehicle handling and safety.

Abstract:

This paper presents the findings of an empirical analysis of a roll-plane Hydraulically Interconnected Suspension (HIS) system under vehicle articulation mode excitation. The articulation mode of a four-wheel vehicle describes the in-phase motion of two diagonal opposed wheels, with adjacent wheels moving out of phase. This mode is critical for better off-road vehicle handling, particularly in utility vehicles; nonetheless, only little research has been conducted addressing this issue. Although a soft articulation mode is desired for enhanced road-holding, the widely used anti-roll bars, necessary for increased roll stiffness, also make the articulation mode stiffer. As a result, one or more wheels may lose ground contact on uneven surfaces, compromising vehicle stability and safety. Roll-plane HIS systems are capable of decoupling vehicle roll from articulation at full-car level; thus HIS systems are attracting ongoing attention from researchers. A comparative experimental study of HIS and anti-roll bars has been carried out on a purpose-built four-post dynamic suspension test rig in order to evaluate vehicle dynamic performance in both roll and articulation modes. For this the vehicle is tested at two different configurations: conventional suspension and roll-plane HIS. Consequently, it has been demonstrated that the HIS system offers a significantly softer articulation mode compared to conventional anti-roll bars, improving vehicle handling and safety. A detailed analysis and discussion of test results conclude this paper.
