TEAMER: Laboratory Upgrade Point Absorber v2 CAD Model and Bill of Materials
The Laboratory Upgrade Point Absorber (LUPA) is an open-source wave energy converter designed and tested by Oregon State University. The computer-aided design (CAD) files are provided here in two forms: the original SOLIDWORKS (2024) model as "LUPA SOLIDWORKS.zip" and as a STEP file "LUPA-A1000.step". The bill of materials is provided as an Excel file with assemblies (LUPA-Axxx), part numbers (LUPA-Axxx-Pyyy), part descriptions, manufacturers, and manufacturer part numbers. An engineering drawing is provided as a PDF of the basic float and spar geometries and mass properties.
This comprehensive CAD model represents LUPA as it was deployed in Fall 2023 testing (project name: TEAMERLUPA2) at the O.H. Hinsdale Wave Research Laboratory. The mass properties, including mass, center of gravity, and moments of inertia, have been overridden for some parts and assemblies to match the physical device properties as determined from experiments. This appears as "overridden by user" when viewing mass properties in SOLIDWORKS. The LUPA-A1000.SLDASM file from the LUPA SOLIDWORKS.zip folder is the topmost assembly; open this file to see the entire model as one assembly.
This model is the second published CAD model of LUPA. The first is linked below as Version 1. This second model has the following engineering changes: moved spar flotation up, added more mass to the heave plate, added the MiniDAQ to the float, and reduced the weight of the PTO pulleys. The net effect of these changes makes LUPA more hydrodynamically stable than the first version.
See "PMEC Page" and the "Signature Project Page" resources below for more information on LUPA. This testing was funded by TEAMER RTFS 7. Data from this testing can be found on MHKDR at the links below.
