The invention discloses a verification system of a multi-axle vehicle wheel positioning parameter measuring basis detector, and aims to solve the verification problem of the multi-axle vehicle wheel positioning parameter measuring basis detector. The verification system of the multi-axle vehicle wheel positioning parameter measuring basis detector is mainly composed of a coordinate plate (1) and a simulated frame (2). The end of a steel frame at the upper part of the simulated frame (2) is placed vertical to the coordinate plate (1) and magnetically connected with the coordinate plate (1). The verification system of the multi-axle vehicle wheel positioning parameter measuring basis detector is small in space occupation, simple in structure, high in detection precision, simple and convenient in operation, easy to install, low in cost and reliable in performance.
