Seat-related discomfort and health problems, which occur especially during long rowing tours or training sessions, can be reduced by rowing seats with a surface geometry that is ergonomically optimized for the particular rower. This seat optimization can be done by analyzing measured pressure distributions and modifying the standard seat surface geometry for a specific person based on these results using CAD tools. The project presented here focuses on the purely virtual development of the optimal geometry for specific rowers. FE simulations were performed using Human Body Models (HBMs) to define seat geometries for specific individuals. Human body models were personalized using the scaling module of the PIPER toolbox, the ANSUR database and anthropometric measurements of male rowers of the Ulmer Ruderclub Donau e.V.. Metadata for THUMS 5 version 5.0.3 was developed for this virtual process. For the GHBM M50-0 version 4.5, publicly available metadata was used. A scaling procedure was defined and the results of the scaling process were compared for the two different baseline models. Finally, these different personalized HBMs were used to define user-specific seats for the rowers through simulation. The resulting seat geometries were compared for different rowers.
