Research on curve fitting technology for saxophone bell profile

This paper researched the curve fitting principle and structural characteristic for saxophone bell.And obtained the fitting parametric equation and curve about saxophone bell with MATLAB.In order to obtaining smooth transitional junctions for these segmental curves,revised the fitting parametric equations for saxophone bell.On the basis of the revised parametric equation,established the three dimension parametric model of saxophone with Pro/E.The parametric model lay a well foundation for the optimization design and shape mold design of saxophone in production practice.
