Method and arrangement for measuring and testing a vehicle frame

A method for measuring and testing a vehicle frame, comprising the steps of:

• locating a measurement device which has a radiation source and a radiation detector in front of the frame,
• emitting radiation from the radiation source in a direction toward the frame onto a reflector support having at least one reflector, the reflector being assigned to a part of the frame and the assigned reflector being held on the frame part,
• reflecting the radiation from the reflector onto the radiation detector, and
• determining local coordinates of the reflector with the measurement device at different measurement sites of the frame part, an essentially undeformed section of the frame part being determined from measurement points which have been obtained in this way and
• using the distance of measurement points from the undeformed section as a measure of deformation of the frame,
• wherein the reflector support, in a horizontal transverse direction, has a first outer reflector and an opposite second outer reflector, the distance between the outer reflectors being adjustable such that the outer reflectors have a continually identical distance relative to the geometrical center of the reflector support, the two outer reflectors being assigned to outer frame parts which are provided on opposite longitudinal sides of the frame and wherein the local coordinates of the outer reflectors are determined jointly by the measurement device.
