Abstract
A method of unbalance measurement of a rotary member for balancing thereof in first and second compensating planes includes the steps of: performing test runs wherein the rotary member is rotated about is axis with test weights on the rotary member rotating in different planes thereof, the planes being perpendicular to the axis of rotation of the rotary member, and in each test run the effects of centrifugal forces produced by the test weights are measured simultaneously in more than two measuring planes which differ from the planes in which the test weights rotate so as to provide correlation coefficient matrices in the respective measuring planes; evaluating all of the determinants associated with a given type of rotary member; and ascertaining unbalance vectors of a rotary member of a given type in the respective measuring planes by use of the measuring planes which are determined by the correlation coefficient matrix whose determinant is greatest for that type of rotary member.
