ABSTRACT:
A vehicle excitation testing system and method can include a device for simulating a vehicular motion and vehicular vibration and then measuring response. The system is designed to test front and/or rear wheel sections of a vehicle. The testing system can include a vehicle suspension system including a wheel and chassis, an excitation actuator connected to the suspension system, and a dummy or a real vehicle body linked to the suspension system and having a frame. The frame can be positively attached to the ground surface or floor or other similar isolated and stable base surface. Measuring devices can be connected to the frame, suspension and/or wheels. When the vehicle is excited to simulate road and other conditions, the wheels, suspension system and the vehicle body vibrate. Measurement of these transmitted vibrations can be studied in order to determine how to best control unwanted or unnecessary vibrations in the vehicle.
