Method for correcting a misalignment of at least one shaft train of a drive train on a test bench , wherein at least one piezoelectric force sensor is arranged in a force path via which a force can be transmitted by means of the shaft train (5; 5a, 5b) during a power transmission between a load machine (14; 14a, 14b) of the test bench and a prime mover of the drive train or of the test bench , comprising the following operating steps: performing a force measurement in at least one plane (A, B; F) and/or normal to said at least one plane (A, B; F) which is intersected by an axis of rotation (D) of the shaft train (5; 5a, 5b) and is preferably arranged at least substantially normal to the axis of rotation (D); analyzing a measured value or a sequence of measured values of the force measurement for detecting a misalignment of the shaft train (5; 5a, 5b); determining target values for a position correction of the load machine (14; 14a, 14b) or the prime mover to minimize the misalignment; wherein the target values indicate a direction and an amount by which a component to be aligned is to be displaced and/or rotated, or indicate an absolute value of a direction and a position to which the component to be aligned is to be displaced and/or rotated; wherein for determining the target values the following two further operating steps are carried out: determining (103-1) bending moments or a sequence of bending moments on the shaft train (5; 5a, 5b) on the basis of the measured value or the sequence of measured values of the force measurement; determining (103-2) a bending moment diagram of the shaft train (5; 5a, 5b) on the basis of the determined bending moments or the sequence of bending moments, wherein the target values are determined by means of the bending moment diagram; and outputting the target values. performing a force measurement in at least one plane (A, B; F) and/or normal to said at least one plane (A, B; F) which is intersected by an axis of rotation (D) of the shaft train (5; 5a, 5b) and is preferably arranged at least substantially normal to the axis of rotation (D); analyzing a measured value or a sequence of measured values of the force measurement for detecting a misalignment of the shaft train (5; 5a, 5b); determining target values for a position correction of the load machine (14; 14a, 14b) or the prime mover to minimize the misalignment; wherein the target values indicate a direction and an amount by which a component to be aligned is to be displaced and/or rotated, or indicate an absolute value of a direction and a position to which the component to be aligned is to be displaced and/or rotated; wherein for determining the target values the following two further operating steps are carried out: determining (103-1) bending moments or a sequence of bending moments on the shaft train (5; 5a, 5b) on the basis of the measured value or the sequence of measured values of the force measurement; determining (103-2) a bending moment diagram of the shaft train (5; 5a, 5b) on the basis of the determined bending moments or the sequence of bending moments, wherein the target values are determined by means of the bending moment diagram; and outputting the target values. determining (103-1) bending moments or a sequence of bending moments on the shaft train (5; 5a, 5b) on the basis of the measured value or the sequence of measured values of the force measurement; determining (103-2) a bending moment diagram of the shaft train (5; 5a, 5b) on the basis of the determined bending moments or the sequence of bending moments, wherein the target values are determined by means of the bending moment diagram; and outputting the target values. <EOS>
