Abstract:
This work presents a method for analyzing the noise and vibration problem caused by hydraulic pumps in power steering system of vehicle. This methodology is based on experimental research and coherent analysis of observed system. Experimental investigations are conducted in order to determine dominant excitation of hydraulic system. Measurements were performed in different operating conditions: pump number of revolution was constant and was varied, too. Pressure of oil in hydraulic system is varied too. A new method of assessment and determination of dominant NVH pump excitation is presented. Experimental results are used as input and output data coherent analysis. Obtained results showed that number of measuring channels can be reduced, especially in high frequency domain. Obtained results can be used in experiment design.
