title = "Investigations on the Human Body and Seat Suspension Response Using Quarter, Half and Full Car Models",
abstract = "A number of human body and vehicle models have been developed to study vehicle and human dynamics. Which combination of these models is appropriate is an open question since it requires a compromise between modeling complexity and simulation accuracy. This paper attempts to answer this question by combining previously developed 12 degrees of freedom (DoF) human body and nonlinear cushion contact force models with quarter car (2-DoF), half-car (4-DoF) and full car (7DoF) models through a seat suspension system with an inclined multi-compression damper. The seat suspension parameters are obtained using a genetic algorithm (GA) based optimization exercise which minimizes seat effective amplitude transmissibility (SEAT) factor for random and bump road profiles. These systems are then analyzed using MATLAB-SIMULINK for pitch and roll. Various response parameters such as seat acceleration, cushion contact force, head fore-aft and vertical acceleration have been studied with different vehicle models and road profiles. The results indicate clear inferior outcomes of the quarter car model and thus advises avoiding them for integrated driver-vehicle ride comfort analysis.",
