Research Acoustics

Machinery generating or transmitting torque can contribute significantly to the noise emissions of a mechanical system. To assess potentials for reducing acoustic signatures in marine propulsion systems, Renk and Geislinger have conducted tests on a Renk Advanced Electric Drive and a Geislinger Silenco coupling. This topic will be presented at the 2nd Torsional Vibration Symposium, 17th to 19th May 2017, Salzburg, Austria.

1 Motivation

Continued and increasing demand for quiet propulsion machinery exists in the shipbuilding industry. For research vessels the aim is to improve fish avoidance behaviour and signal-to-noise ratios for acoustic surveying. For yachts, the end-customer expectation may be shaped by onshore building noise levels, while for navy vessels low detectability is the major consideration.

Major sources of noise in ships are breaking surface waves, vibrations excited by the hydrodynamic interaction of the propeller and the noise of machinery transmitted and radiated by...
