Abstract
A method for developing a tire model for use with an effective road profile in testing an automotive vehicle on a spindle-coupled road simulator defines a flat surface road plane in a three coordinate reference system to represent the effective road profile with the three coordinates comprising a plane vertical deflection, a plane radial contact angle, and a plane lateral contact angle. The tire is then excited over a predetermined range while on a tire test apparatus for developing the tire model. The tire test apparatus includes a flat tire contact plane moveable so as to contact the tire, the flat tire contact plane defining a three coordinate reference system to represent the effective road profile in the three coordinates.
