The paper describes some apparatus which has been developed to measure those characteristics which are of interest in vehicle ride and handling. These are:
Vertical, lateral and fore-and-aft tyre stiffnesses and damper characteristics. Suspension spring rates and friction, suspension geometry and suspension roll stiffnesses. Steering gear geometry and dynamic characteristics, moments and products of inertia of the vehicle and vibration characteristics of the seats.
Some relevant theory and sample results are included in the Appendices.
