<p>The present invention provides a drive-train testing system that is capable of generating a large drive torque without increasing the size of a motor that simulates an engine. The drive-train testing system (1) inputs a drive torque, which is generated according to a torque command which contains an alternating-current component having an excitation frequency, to an input shaft (S1) of a workpiece (W) in order to evaluate the performance of said workpiece (W). This system (1) is equipped with: a first motor (2a); a second motor (2b) that is connected to the drive shaft of the first motor (2a) at one end of the drive shaft of the second motor while connected to the input shaft (S1) of the workpiece (W) at the other end; a torque meter (6) for detecting a torque which acts upon the shaft between the workpiece and the second motor; and a resonance suppression circuit (5) that divides the torque command into a first torque command for the first motor (2a) and a second torque command for the second motor (2b) so as to suppress torsional resonance on the basis of a value detected by the torque meter (6).</p> |
