Method and device for the diagnosis of characteristic vibrations in a mechatronic system

摘要

A method for the diagnosis of natural vibrations in a mechatronic system, includes at least one rigid body (WT1, WT2), which is moved relative to another rigid body (S) by means of at least one numerically-controlled drive, whereby the natural vibrations are caused by the drive (A1, A2) and are detected by sensors (WM1, WM2, N1, N2, BA1, BA2,) internal or external to the system. The drives (A1, A2) can be used as a system-internal, vibration-generator, so-called rotatory shakers, by superimposing white noise on a constant speed for the drive, or by wobbling the frequencies.
