Abstract
Torsional springs are often created by a single fundamental spring design despite the application differences. The limitation of the spring output is constrained by the low number of fundamental designs of the torsional spring in some aspects, such as manufacturing complexity and limited application. This also leads to limited in the design development of torsional spring. A new torsional spring design is introduced in this paper. B-spline-based torsional springs can provide lower manufacturing complexity compared to generic torsional spring designs. This paper introduces a methodology to create single B-spline torsional springs which can provide the desired spring output. The springs were created by a combination of mathematical and physical simulation tools. A B-spline curve is used to determine a spring shape, while the Genetic algorithm and Finite element analysis are used for design optimization and verification. The present method is used to create two spring types, including constant-torque and cosine-torque, to evaluate the performance of the methods used.
