The hybrid vibration experiment, in which an actual model of part of a vehicle excited by an actuator and vibration analysis of a numerical model are simultaneously conducted by exchanging information with each other, is being developed and tested. We have applied this experimental method to the vibration analysis of a suspension vehicle system excited by a roadsurface pattern. By using a quarter model of a vehicle with two degrees of freedom, we established an experimental system that consists of a hydraulic actuator which excites the suspension, a digital signal processor which calculates the response of the numerical model and generates reference signals for the hydraulic actuator, and a load cell which measures the reaction force of the suspension. We did trial tests on this experimental system and found its simulated results agree well with corresponding experimental measurements.
