Helical torsion springs made of the round spring wire are often used as the drives providing mutual rotation of parts in the single-action mechanisms in rocket and space applications. The considered methodology of torsion spring design computation makes it possible to determine the range of design values based on the specified initial parameters, where conditions of the spring strength and the mechanism deployment reliability are satisfied. This methodology allows avoiding the “trial and error” approach from multiple alteration and recomputation of the spring parameters initially specified or obtained during the computation. It makes it possible to create an effective computation algorithm in the targeted and consistent search for satisfactory solutions in designing spring units and mechanisms with the required operability and reliability (dimensions, ability to overcome resistive forces on the motion path, displace the control objects to the required distance and strength). Based on the computation algorithm, a program is created for design and verificational computation of the helical cylindrical torsion springs making it possible to quickly find the effective solutions in practical activities of designers and computation engineers.
