Development of Parametric Tool to Design Base Frame for Marine Application Engine
To be published on April 2, 2019 by SAE International in United States
A spread sheet based parametric tool is developed to design the base frame for a marine genset. Factors such as engine details, alternator details, anti-vibration mount (AVM) etc., that determine the design of the base frame, are set as parameters in the spreadsheet. The spreadsheet has formulae to calculate channel specifications, and anti-vibration mount deflections. It is linked to channel standards database and selects the optimal channel based on calculations. Similarly, the tool provides guidance in selection of anti-vibration mounts (AVM) from supplier catalogues, helps to predict number of anti-vibration mounts required and their location on base frame. This spread sheet is integrated with a generic base frame 3D model and 2 D print in Creo, which is auto-updated based on calculated parameters in the spreadsheet. Using this tool the user can generate a 3D-model and 2D print. This tool helps to standardize the design process and reduces design turnaround time considerably. The output of the tool and existing base frame designs were analysed using a finite element tool (ANSYS). Modal and static analysis were performed and results were observed to be within ± 15%. This tool will be developed further and validated for base frames in other applications like rail.
