The mathematical support of reinforced hose (RH) CAD is considered, namely, RH mathematical models used for strength calculations. The relevance of the study is due to the need to expand the RH design automation. Only automation tools for general engineering are used currently in this area: CAD for geometric modeling, general CAE analysis systems. CAE modules oriented to work with composite materials, appeared in the last decade, are based on finite element models obtained from geometric models. The aim of the paper is to create RH analytical models suitable for strength calculations. Such models for six RH designs are obtained and considered. Conclusions are drawn that the obtained models, implemented into specialized CAD module, can be used to accelerate RH preliminary design.

Key words: strength calculations, composite materials, chemical engineering, specialized CAD, mathematical modeling.
