Abstract
This research presents an analytical study of development of three-dimensional vehicle model to be able to examine the consumption energy of vehicle motion by functional modeling method. The three dimensional vehicle model was constructed by applying functional model, this paper by using functional modeling method, was constructed model of the damper and the viscous damping of the suspension, the calculation of the energy consumption due to frictional force between the spring and damper suspension is possible. Shows the validity of the model vehicle vibration, and transient response was verified in the road surface plane. Running a flat road surface was created based on the data measured on the highway road surface, to calculate the energy consumption of the suspension. I was able to confirm that the change in the rate varies depending on the transient response, the amount of energy consumption of 40km per hour we are, 60km per hour and 80km per hour.
