Hydraulically operated components are found in all segments of industry and can form a key transfer path for discernible noise and vibration phenomena. In these cases, connected pumps and hydraulic hoses have to be uncoupled to avoid any transference to the overall system, for example to a vehicle.
As well as investigating the airborne sound phenomena of hydraulic pumps, vibration behavior is another point of interest due to the pulsation excitation in the hoses.

All the airborne and structure-borne sound phenomena of entire composite systems can be recorded and evaluated with PAK systems by using the PAK applications for:

  • Investigating pulse-containing signals;
  • Visualizing the deflection shape; and
  • Analyzing rotation-related signals.

The shaker excitation and excitation with an impulse hammer can also be used to examine the coupling of hoses and pumps.

We provide all the necessary tools in one single system. PAK systems have a modular design and can be extended to accommodate the user’s tasks.
