Method for Analyzing Coherence on Vibration between Vehicle Components And System Using The Method

摘要

To analyze the vibration contribution between the components in the GDI vehicle of the present invention is capable of processing computing the mathematical operations the method comprising the device receives the measured values from the vibration of the vibration sensor attached to each of the surrounding parts and the target part, the computing device is calculating the power spectral density of the oscillation value, the computing device is the to determine the correlation between the degree of the vibration in the surrounding parts, and calculating a correlation between the computed power spectral density, is also a correlation between the calculated peripheral parts according to the multi-dimensional spectral analysis in the computing device is mounted removed, each peripheral parts, and the step includes the step of computing device for computing a pure vibration contribution that contributes to the target part quantify the contribution calculated by the pure vibration of each peripheral part. ;
