Publication number: 20130200264Abstract: A method for measuring and testing a vehicle frame (15), in particular a commercial vehicle or bus frame, wherein a radiation source and a radiation receiver are arranged in front of the frame (15) and radiation is beamed from the radiation source toward the frame (15) and onto a reflector support (1) having at least one reflector (2, 3, 4, 5). The reflector (2, 3, 4, 5) is assigned to a part of the frame (15), and the radiation is reflected by the reflector (2, 3, 4, 5) to the radiation receiver and a measuring device determines location coordinates of the reflector (2, 3, 4, 5) at different measuring points of the frame part. A substantially non-deformed section (A) of the frame part is ascertained from the resulting measuring points (P) and the variation of the measuring points (P) from the non-deformed section (A) is determined.Type: ApplicationFiled: September 21, 2011Publication date: August 8, 2013Applicant: HAWEKA AGInventors: Dirk Warkotsch, Alexander Eberle, Tilo Janz, Harald Schenitzki
