Project Working to Validate Noise Modeling Techniques in Fluid Power Applications

The fluid power research projects coming out of the Center for Compact and Efficient Fluid Power (CCEFP) have continued to progress, and all ten of the newly funded projects were presented at the CCEFP Industry-University Summit in April 2017. The Investigation of Noise Transmission through Pump Casing project was presented by Paul Kalbfleisch, a researcher at Purdue University. The project has aimed to validating noise modeling techniques, specifically applied to swash plate type axial piston machines, through incremental experimentation.

Project Premise: This project has focused on noise modeling techniques for swash plate type axial piston machines. The optimized models are being validated by experimental results. It will contribute to the existing body of knowledge for how noise is both generated and transmitted through fluid power components.

Recent Progress and Next Steps: So far, the experimental results have supported that pump harmonic frequencies below 5,000 Hz are the dominant frequencies of audible noise. Next steps in the project include:

  • Verifying the current hydraulic model by measuring displacement chamber and port pressures.
  • Modeling the forced response.
