Scientific Forming Technologies (SFTC) have released their Winter 2017 newsletter, which focuses on bicycle saddle design. Using clear examples, it shows how the features and capabilities available in DEFORM V11 now make it practical
Human tissue modeling has traditionally been the territory of general purpose finite element codes. General purpose codes are quite capable, but often sacrifice ease of use for flexibility. Mesh generation, non-linear contact analysis, and coupling of multiphysics processes can all be arduous. Recently, DEFORM was selected for its ease of use and flexibility in order to study the interaction of human tissue with the foam padding and underlying structure of a high performance bicycle saddle.
High performance bicycle saddle design is challenging. Saddles need to support high pressure and provide a firm link to the bike. Too much foam, comfortable for a recreational rider, means a “squishy” link and lack of control for a performance rider. Too little foam results in high pressure and discomfort. Excessive foam in the wrong areas can injure nerves and soft tissue. Balancing foam distribution becomes a critical exercise in saddle design.
