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.

What is claimed is: 1. A method for using a vehicle excitation test apparatus, comprising: providing a vehicle located adjacent a ground surface, the vehicle including a vehicle frame, at least one vehicle wheel, a longitudinal axis extending along a drive direction of the vehicle, and a vertical axis perpendicular to the longitudinal axis and the ground surface; applying a vertical preload to at least one of the vehicle frame and the at least one vehicle wheel; applying a longitudinal preload to at least one of the vehicle frame and the at least one vehicle wheel; applying a vibrational input to at least one of a first portion of the vehicle frame and the at least one vehicle wheel; rigidly securing a second portion of the vehicle frame to the ground surface such that the second portion of the vehicle frame does not substantially move with respect to the ground surface during the applying of the vibrational input; and measuring reaction to the vibrational input at at least one of the vehicle frame and the at least one wheel. 2. The method for using a vehicle excitation test apparatus of claim 1, wherein the second portion of the vehicle frame is a rear portion of the vehicle frame, and the first portion of the vehicle frame is a front portion of the vehicle frame. 3. The method for using a vehicle excitation test apparatus of claim 1, wherein applying the vertical preload and applying the longitudinal preload include applying the vertical preload to a front wheel of the vehicle and applying the longitudinal preload to a front wheel of the vehicle. 4. The method for using a vehicle excitation test apparatus of claim 3, wherein the applying of a vibrational input occurs at a front wheel of the vehicle. 5. The method for using a vehicle excitation test apparatus of claim 1, wherein the applying of a vibrational input is accomplished through the use of a shaker attached to the at least one vehicle wheel. 6. The method for using a vehicle excitation test apparatus of claim 1, wherein the applying of a vibrational input is accomplished through the use of an air bearing located adjacent the at least one vehicle wheel. 7. A system for conducting excitation tests on a vehicle located adjacent a ground surface, comprising: a vehicle including a vehicle frame and at least one vehicle wheel, the vehicle including a longitudinal axis extending along a drive direction of the vehicle and a vertical axis perpendicular to the longitudinal axis and the ground surface; a longitudinal preload structure configured to apply a longitudinal preload to at least one of the vehicle frame and the at least one vehicle wheel; a shaker attached to at least one of a first portion of the vehicle frame and the at least one vehicle wheel; an attachment structure rigidly securing a second portion of the vehicle frame to the ground surface such that the second portion of the vehicle frame does not substantially move with respect to the ground surface during operation of the shaker; and a measuring device located adjacent the vehicle and configured to measure vibration at at least one of the vehicle frame and the at least one wheel. 8. The system for conducting excitation tests on a vehicle of claim 7, wherein the second portion of the vehicle frame is a rear portion of the vehicle frame, and the first portion of the vehicle frame is a front portion of the vehicle frame. 9. The system for conducting excitation tests on a vehicle of claim 7, wherein the longitudinal preload is connected to a front wheel of the vehicle. 10. The system for conducting excitation tests on a vehicle of claim 7, wherein the shaker is connected to a front wheel of the vehicle. 11. The system for conducting excitation tests on a vehicle of claim 7, wherein the shaker includes an air bearing. 12. The system for conducting excitation tests on a vehicle of claim 11, wherein the air bearing is located adjacent the at least one vehicle wheel. 13. The system for conducting excitation tests on a vehicle of claim 7, wherein the shaker is attached to the at least one vehicle wheel. 14. The system for conducting excitation tests on a vehicle of claim 7, wherein the attachment structure includes a bar with a first fixing structure located at a first end of the bar and a second fixing structure located at a second end of the bar, and the first fixing structure is attached to the vehicle frame, and the second fixing structure is attached to the ground surface. 15. The system for conducting excitation tests on a vehicle of claim 7, further comprising: a vertical preload structure configured to apply a force to at least one of the vehicle frame and the at least one vehicle wheel. 16. The system for conducting excitation tests on a vehicle of claim 15, wherein the vertical preload is connected to a front wheel of the vehicle. 17. The system for conducting excitation tests on a vehicle of claim 7, wherein the shaker includes an electronic or hydraulic vibrator. 18. The system for conducting excitation tests on a vehicle of claim 7, wherein the attachment structure includes a cement wall.
