Vibrational behaviour of fluid power systems is a very important aspect regarding lifetime of the components and especially noise problems within hydraulic circuits. Vibration emitting and noise generating elements of primary evidence especially in hydraulic systems are pumps. In completed hydraulic circuits it is often seen that even vibration and noise-optimised pumps show noise problems due to the inter-activeness of all system components built in. Noise problems can be investigated wit...Vibrational behaviour of fluid power systems is a very important aspect regarding lifetime of the components and especially noise problems within hydraulic circuits. Vibration emitting and noise generating elements of primary evidence especially in hydraulic systems are pumps. In completed hydraulic circuits it is often seen that even vibration and noise-optimised pumps show noise problems due to the inter-activeness of all system components built in. Noise problems can be investigated with several vibration and noise measurement methods, which are mostly based on the analysis of the noise relevant frequency spectre of the vibration emitting source and the evaluation of frequencies which are of maximum influence. A precise analysis of the phenomena gives the basis to eliminate one or more of the dominant noise frequencies with the help of hydraulic silencers.» weiterlesen» einklappen
