摘要
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 multiple coordinate reference system to represent the effective road profile. The coordinates comprise at least four of a plane vertical deflection, a plane radial contact angle, a plane lateral contact angle, a steer contact angle, a lateral displacement and a longitudinal displacement. A tire is excited over a predetermined range while on a tire test apparatus for developing the tire model. The tire test apparatus includes an articulated running flat belt platform moveable so as to contact the tire, the flat tire contact plane defining a coordinate reference system to represent the effective road profile in multiple degrees-of-freedom.
