Abstract: Tubular springs have received the name “Manometric” thanks to their initial use in manometric devices. For the wide use of tubular springs in various spheres of human activity, relevant methods of calculating their static and dynamic characteristics are needed. Many works have discussed the study of manometric tubular springs. The main method for calculating static characteristics of springs is the semi-membrane theory of shells, and to calculate the frequencies of natural oscillations, the spring was considered as a rod with a deformable cross-section. The article considers algorithms for calculation of static characteristics and frequencies of natural oscillations of manometric tubular springs with known geometric parameters of a spring and physical properties of a material. For calculations, in general, numerical methods were used, so for their implementation, it was required to develop programs for automatic design, in which the algorithms are implemented. The article describes the software systems for calculating the characteristics of springs: “Module” and “PCRMTP”, which allow investigating the stress-strain state of the cross-section of tubular springs, determine their static characteristics with known geometric parameters, spring material, internal pressure and operating conditions. In addition, in the complex “PCRMTP” the possibility of calculating the frequencies of natural oscillations of tubular springs is realized. The automation of the design of tubular springs significantly reduces the labour input of selecting springs with the necessary characteristics and thereby eliminates the deterrent factor of introducing new designs.
