Abstract

A flexible lofting spline is presented as an actuated component in mechanical systems requiring the forming of continuous shapes. The spline is modeled with a piece-wise, cubic polynomial, based on minimum elastic strain energy, and nonlinear, large deflections. A flexible spline test device is explained and used to evaluate accuracy, limitations, and general issues. Conclusions and recommendations are provided.
