Mass Correlation Between Real Vehicle and Vehicle Laboratory Simulation Model

The problem how easily to scale down real object of simulation to laboratory simulation model, thus simplify equations to the extent of only one scaling factor that correlates between the real object and model, is always present in laboratory simulations. This paper presents a simple way to scale down real vehicle to the model level and also how to determine the acceptable range of real vehicle that can be simulated by laboratory model. The problem started when all field measurements on real vehicle ended, and laboratory simulation model, smaller than real vehicle, had to simulate that vehicle (drive machine had less rated power than a vehicle engine, and a load machine can create less load that of a real vehicle).
