“…Thus, the variation of the sprung mass has a more significant effect on passenger discomfort than variation of the unsprung mass. These results correlate with that obtained by Blundel (1999) on modeling and simulation of vehicle handling, Senthilkumar and Vijayarangan (2007) on analytical and experimental studies on active suspension system of light passenger vehicle to improve comfort, Olatunbosun and Dunn (1991) in simulation model for passive suspension ride performance optimization; and Paddan and Griffin (2002) on the effect of seating on exposure to whole-body vibration.…”

“…The half-car model is used because it takes into account both translational bounce motion about any axis) and rotational motions (pitch motion about the y axis) of the sprung mass. This assumes the car is symmetric about the longitudinal axis and also assumes equal suspension characteristics for both front wheels and rear wheels (Olatunbosun and Dunn, 1991). This is shown in Figure 2.…”

“…Methods for assessing the transient response of a vehicle include computer simulation (Sharp and Hassan, 1986) or theoretical analysis by mathematical modeling (Thompson, 1989) or experimental testing either on the road or on the ride simulator in the laboratory (Olatunbosun and Dunn, 1991). Computer aided analysis is fast becoming an important tool in the development of suspension system.…”

“…Computer aided analysis is fast becoming an important tool in the development of suspension system. One of such tools are based on Matlab/Simulink software which has been adopted and implemented by several researchers to analyze the response of vehicles traversing road irregularities (Olatunbosun and Dunn, 1991).…”

Considering that many Nigerian roads are untarred, the effect of frequent plying of these untarred roads on passengers and the expected performance of suspension system of vehicles are important for health and safety reasons. This is significant because the transmission of vibration associated with suspension systems are dependent on the frequency spectrum of the road input, and the nature of the suspension system and the vehicle seating arrangement that is producing the vibration. Thus, this study focuses on the discomfort experienced by passengers based on parametric study of vehicle with semi-active suspension system under transient road conditions. The modeling of the of semi-active vehicle suspension system properties are contrived on the mass- spring damper system for 4 degree-of–freedom half- car model integrated with 3 degrees of freedom human-seat arrangement. Using vehicle parameters, the severity of ride discomfort experienced by the passenger as the vehicle traversed transient road conditions (i.e., traversing obstruction) was evaluated in terms of the vibration dose value (VDV). Results of simulation based on the parametric studies are presented and the vibration dose values evaluated to show the dependence of vehicle ride comfort on the characteristics of the various elements of the vehicle suspension such as stiffness and damping characteristics. The result showed that the variation of sprung mass and suspension stiffness of the vehicle had more significant effects on passenger discomfort than the variation of the unsprung mass. The parametric study also revealed that suspension stiffness affects the suspension working space as the vehicle traversed transient road condition.

“…Note that the behaviour is governed primarily by the first mode natural frequency, and that other combinations of properties achieving the same natural frequency will produce similar beam responses. The vehicle mass is taken to be 1000 kg, and according to Heller et al 26 . an optimised suspension stiffness is within the range 41–45 kN/m, hence in this paper a value of 45 kN/m is used.…”
