A device for the evaluation of vibrations (10) comprises an evaluating device (12), which comprises an input for introducing a vibration signal (SG) and is designed to determine a characteristic signal (BK) with the dimension of length/timeβand/or the square (SE) of the characteristic signal (BK) from the vibration signal (SG) by means of a frequency-dependent evaluation of the vibration signal (SG). For a predefined value of a dimensional exponentβ, 1.3<β<1.7, a vibration sensor (11) of the device (10) outputs the vibration signal (SG). An RMS value (BEF) of the characteristic signal (BK) or the square (SE) of the characteristic signal (BK) essentially corresponds to the damaging effect of the vibrations on a structure or a machine. The square (SE) can be converted into a service life (T) according to the equation T=KB/SE and displayed. |
