摘要： Embodiments of a process for estimating a rotational speed of a rotating component and a process for estimating an acceptable rotor imbalance of a rotating component are provided herein. The process for estimating the rotational speed of a rotating component for a charging system comprises measuring a vibration signal of the rotating component by means of a sensor; and identifying harmonic train members from a plurality of peaked components of the vibration signal. Further, the process comprises determining a candidate fundamental frequency from the harmonic train members; and determining a derived vibration amplitude value from the vibration signal. This determination involves a filtering of the vibration signal, removing periodic contributions having a high amplitude. A scalar value is then derived from the filtered signal as a derived vibration amplitude value, representing the integrated total vibration amplitude of the filtered signal at the current speed. The process comprises verifying a consistency condition between the derived vibration amplitude value and the candidate fundamental frequency using a predetermined speed-amplitude map, associating speed values with their respective derived vibration amplitude values. For determining an acceptable rotor imbalance, a speed-amplitude map obtained at a time when the imbalance is acceptable is compared to a speed-amplitude map at a later point in time. An offset between the maps may indicate an inacceptable imbalance.

摘要： The invention relates to a stabilizer channel having an annular stabilizer chamber which encloses a main flow channel in the intake region of a compressor wheel and is delimited from the main flow channel by an annular bridge. The annular stabilizer channel is connected to the main flow channel via a downstream flow inlet and an upstream flow outlet. At least one separating element (T) is arranged in at least one of the flow inlet and the flow outlet, with the result that an inflow into the annular stabilizer chamber and/or an outflow out of the annular stabilizer chamber are/is split transversely with respect to the main flow direction of the main flow channel. At least one flow guiding element is arranged in at least one of the flow inlet and the flow outlet.
