Annotation: The new approach to solve the calculation problem of the stress-strain state of the sensing element of the manometric and thermal devices, that is advisable to apply in the design process is considered in this article. The object of the research is wound manometric spring. The subject of the research is the stress-strain state of wound manometric springs with different shapes of cross-sections. The aim of the study is the creation of mathematical model of the object stress-strain state, which allows, in future, to solve the problem of optimization of its design parameters in the automatic calculation algorithm for the automatic design of springs. As a result of the research, the model of stress-strain state of wound manometric springs was developed, the optimization problem of its parameters taking into account constructive and technological restrictions was formulated and the method to solve this problem was proposed. The area of use is aircraft instruments designed to measure the pressure of liquids and gases.


Keywords: mathematical model, stress-strain state, wound tubular manometric spring, optimization of target function
