APPARATUS AND METHOD FOR THE ROTATION-SYNCHRONOUS MONITORING OF A ROTATING ELEMENT

WIPO Patent Application WO/2019/092240

A3

The invention relates to a method (900) and an apparatus (100) for monitoring a rotating element. The apparatus according to the invention inter alia comprises a signal input (102) which is designed to receive a time-dependent vibration signal s(t) emitted by the rotating element (101) and a rotational speed signal fB of the rotating element (101). The apparatus (100) according to the invention further comprises a signal modification device (103) which is designed to modify the rotational speed signal fB and to output a modified rotational speed signal fA. The apparatus (100) according to the invention also comprises a sampling device (104) which is designed to sample the time-dependent vibration signal s(t) as a sampling frequency using the modified rotational speed signal fA and to generate a discrete-time vibration signal sA(n). The apparatus (100) is characterized in that the modified rotational speed signal fA is a multiple of the rotational speed signal fB multiplied by a real-value factor N.
