Abstract: The invention relates to a method for measuring and calculating geometric parameters of the wheels of a wheelset for rail vehicles, wherein the wheelset to be evaluated is rotatably mounted in a wheelset machine tool or in a wheelset diagnostic system and wherein measured values for profile measurement with respect to profile wear to be detected are determined during rotational motion of said wheelset. The problem addressed by the invention is to expand already available measuring methods on known wheelset machine tools and wheelset diagnostic systems in such a way that further geometric parameters can be detected and evaluated. This problem is solved in that methods for measuring and calculating the equivalent conicity and the radial run-out property of a wheelset are integrated as new measurement functions, wherein solution approaches are proposed for these additional methods.
