DEVELOPMENT OF DISCRETE-CONTINUOUS STRENGTHENING TECHNOLOGY OF AUTONOMOUS TURBOEXPANDER POWER PLANTS ELEMENTS

This paper describes a set of research and development activities to create a technology for discrete-continuous strengthening of autonomous turbo-expander power plants elements. With this purpose, it is proposed to study the stress-strain state of the system of discretely and continuously strengthened bodies in contact. This is done by combining the positive effects observed when using each type of strengthening. The combined effect of this synthetic strengthening method exceeds the sum of the effects of each of the component methods. In order to achieve high technical characteristics of the elements and turboexpander power plants as a whole, an approach based on parametric modelling of structures and technologies has been developed. By targeted improvement of these parameters, strength, efficiency and durability are increased. It also reduces the wear and tear of the most stressed and critical elements of turboexpander power plants. The main feature of the developed approaches to the creation of the discrete-continuous strengthening technology of the elements of autonomous turboexpander power plants is the development and application of a generalized parametric model of turboexpander power plants as a complete system object. At the same time, both design and technological solutions are varied and sought after by the criteria of strength, durability and efficiency..
