Individual vibration damping for complex pump test stands through low-frequency air spring systems

A university of applied sciences team optimises oil pumps to reduce the fuel consumption of combustion motors. Numerous tests are necessary for this. A test stand caused undesired vibrations. PLM air spring elements from ACE ensure damping at several points. The optimum design was achieved with the company-produced measurement case and an external measuring sensor that was connected to a tablet PC. The low-frequency elements provide a significant isolating effect from a frequency of 5 hertz and above, and prove themselves to be significantly more effective than the previously used rubber-metal isolators.
