Abstract This paper reports the systematic development of tape spring hinges for a solar array by an optimization method considering various deployment performances. The nonlinear behavior between the moment and the rotation angle of a tape spring hinge is determined through experimental results rather than through finite element analysis results or theoretical solutions in order to identify the moment–rotation profile accurately. Response surfaces comprising the measured moment–rotation profile and design parameters of a tape spring hinge are generated by a Box–Behnken experimental design. Furthermore, to consider deployment performances such as low latch-up load, latching without overshoot, high deployment stiffness, and high torque margin, the deployment equation is derived by Kane's dynamic equation considering any number of solar panels. The present study proposes a systematic approach for designing tape spring hinges for any number of solar panels; the designed hinges satisfy all design requirements. The approach involves minimizing the cost function including several design requirements and solving the deployment equation containing the response surfaces of the moment–rotation profiles simultaneously. To verify the effectiveness of the proposed approach, several examples are demonstrated.
