Abstract: An apparatus for measuring forces produced by an unbalance of a rotary member 8 includes a support device 3 for supporting the rotary member 8 rotatably about its axis 1, and having at least one measurement sensor 4 placed at a vibratory location of the support device 3, wherein the at least one measurement sensor 4 is designed to measure vibratory accelerations of the location at which the measurement sensor 4 is placed.

Abstract: The invention relates to a method for contactless determining non-uniformities of a loaded wheel, comprising the steps of determining outer contour of at least a portion of the unloaded wheel; simulating loading of the wheel with a virtual loading element bearing against the tyre tread for a plurality of rotary positions of the wheel on the basis of the determined outer contour, a displacement of the determined outer contour caused by the virtual loading element and a predetermined spring rate associated to the tyre tread; and determining non-uniformities of the loaded wheel using the simulation results.

Abstract: The present invention refers to a parameter detection system for detecting in a non-mechanical manner at least one parameter of an object (1) to be examined. The parameter detection system includes a mounting device (2) for holding the object, and a mobile unit (14) which is freely movable and adapted for indicating a position on the object. A sensing means is provided for sensing the position on the object indicated by the mobile unit and for outputting corresponding detection signals indicative of the sensed position. A calculation means (13) is provided for calculating the at least one parameter from the position on object based on the detection signals.

Abstract: A method and an apparatus for carrying out the method are disclosed for hidden spokes placement of balancing weights on a wheel, having a hub, a rim and the hub and the rim being connected by several spokes, comprising determination of spoke configuration data. Now, it is possible to analyze spoke configuration and width of the spokes in details, enabling the weight splitting behind spokes even if spokes are forked, oblique, not equidistant, or they have different dimension.
