The invention relates to a method and a drivetrain test bench for detecting an imbalance and/or a misalignment of at least one shaft assembly of a drivetrain during operation on a test bench, wherein a first piezoelectric force sensor is arranged in a flow of force generated by a transmission of power between a load unit of the test bench and a drive unit of the drivetrain or the test bench, and which is transmitted by of the shaft assembly, wherein the first force sensor realizes a first force measurement in a first plane and/or perpendicular to the first plane as is intersected by a rotational axis of the shaft assembly and preferably at least substantially perpendicular to the rotational axis, and wherein the first force measurement and/or a rotational angle determination for the shaft assembly are used to detect an imbalance, and/or a misalignment of the shaft assembly.

A device, system and method for balancing a rotating object includes a balancing device having a balancing hub removably mounted onto the rotating object and a mass body releasably engaged with the balancing hub at a plurality of equidistant locations along an outer periphery of the balancing hub. A measurement unit is coupled to the rotating object to measure one or both of a vibration phase angle and an imbalance magnitude of the rotating object.
