  • Publication number: 20180328807
    Abstract: The invention relates to a method for determining the root mean square value of a vibration variable that is measured on a machine. A test measurement is carried out in order to obtain a test signal of the vibration variable with a test signal length; the influence of shortening the signal length of the test signal on the associated root mean square value is estimated and the relative deviation of the root mean square value emerging for a shortened signal length from the root mean square value emerging for the full test signal length is estimated therefrom as a function of the signal length to obtain a root mean square value error function; and a measurement of the vibration variable is carried out for determining the root mean square value. The measurement duration of this measurement is selected on the basis of the root mean square value error function.

  • Patent number: 9453760
    Abstract: 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/time? and/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 exponent ?, 1.3<?<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.
