Abstract
Helical cylindrical compression springs are most often used in the one-time actuation mechanisms in rocket and space applications as the push drives to perform useful work in moving detachable parts of the aerospace vehicles. Such drives possess maximum energy characteristics with minimal weight and cost. The paper proposes the pusher spring design calculation methodology making it possible to take into account the design values range determined by the given initial spring parameters, where the strength condition is satisfied. The calculation methodology takes into account the spring design values range and makes it possible to create an effective computational algorithm. It is introduced for a targeted and consistent search of satisfactory solutions in designing spring units and mechanisms with the required performance and reliability (dimensions, ability to overcome resistive forces along the motion path and move control objects to the required distance, as well as strength). Based on the computational algorithm, a software program was created for the design and verifying calculation of the helical cylindrical compression springs, which makes it possible to quickly find effective solutions to be introduced in the practical activities of designers and calculators.
