Propeller Shaft Design
DYNAMIC ANALYSIS OF PROPELLER SHAFT LINES
With a strong background in dynamic systems, we have undertaken dynamic analysis of propeller shaft lines, including whirl frequency analysis and shock analysis.
Our prediction of shaft whirl involved the creation of an Ansys 3D FE model of the propeller, shaft components, journal bearing contact mechanics and the stern structural stiffness to identify resonant frequencies for various shaft speeds and provide static analysis under gravitational loading. We have performed non-linear transient dynamic analysis of safety-critical shaft line components under shock loading in line with industry standards. Our experience extends to the specification of shaft balancing requirements to ensure low noise and vibration.
Supporting new propeller designs
NEW MARINE PROPELLER DESIGNS FOR OPTIMAL PERFORMANCE AND LOW NOISE
Stirling Dynamics is equipped to support development of new marine propeller designs for optimal performance and low noise, ensuring adequate strength and fatigue life. Our experience in rotary fluid dynamics enabled us to utilise industry-leading propeller design software and 3D computational fluid dynamics. Our skilled team of structural design engineers are able to provide detailed design of critical propeller features using SolidWorks 3D CAD software.
We can also conduct static and fatigue analysis of propeller design using 3D FEA for various operational and limit conditions using Ansys.
