The invention relates to a method for detecting at least one shaft system (2; 2 ') of a drive train (3) during operation on a test stand (1). 4a, 4b, 4c), in which a first piezoelectric force sensor (4) is arranged in a force flow, which is caused (101) by a power transmission between a loading machine (14a, 14b) of the test stand (1) and a drive machine (2) of the drive train (3) or of the test stand (1) and which is caused by an imbalance and/or misalignment of the loading machine (14a, 14b) of the test stand (1) by means of a shaft system (5; 5a, 5b), a first force measurement (102-1) being carried out by means of the first force sensor (4a, 4b, 4c) in a first plane (E1) and/or perpendicular to the first plane (E1), the first plane being associated with the axis system (5; 5a, 5b) intersect and preferably at least substantially perpendicular to the axis of rotation (D), and at least one measured value curve for the first force measurement and associated with the measured value curve for the shaft system (5
