Castor (Computer Assessment of Shaftline TOrsional Response) Worksheet v2.0 is a spreadsheet tool that simply and efficiently assesses the key torsional vibration response (natural frequency, peak vibration torque, and stress) of a marine propulsion shaftline for a plant equipped with one of the offered slow speed two-stroke diesel engines. The main features of the presented tool are its low number of input data, simple user interface, and meaningful availability of results. This spreadsheet application is intended as a tool to aid machinery designers during the preliminary design phase of a propulsion shaftline. It provides sufficient information to enable designers to select the proper shaftline dimensions concerning its torsional vibration behavior. The internals behind the spreadsheet front-end include a number of simple regression metamodels built by processing the results database of already performed torsional vibration analyses. |
