FUNDAMENTALS OF MODULAR DESIGN OF PROSPECTIVE NEW GENERATION PASSENGER SLEEPING WAGONS

Purpose. The aim of the work is to study the directions for creating promising competitive passenger sleeping wagons based on the application of the principles of their modular design. Methodology. The research is based on the analysis of literature sources, formation of a system of wagon modules and development on their basis of possible variants of modular design of passenger sleeping wagons and assessment of prospects for their application based on mathematical analysis of the degree of unification of car designs. Findings. In the course of research, it was established that the design of promising passenger sleeping wagons of the new generation should be based on the principles of significantly improving the quality and comfort of passenger transport based on the use of new layout schemes and relevant principles of modular design. The basic geometric module of passenger wagons of any functional purpose assumes increase in width of its body of 3,4 m. Systems of modular design of passenger sleeping wagons in several variants developed on the basis of the offered new layout schemes providing application of two lateral or only one vestibule located in one end wagons or in the middle of their bodies. The proposed layout schemes also provide for increasing the width of longitudinal passages in passenger rooms, equipping wagons with different numbers of bathrooms depending on the type of wagons for their intended purpose, equivalent in size parameters berths in reserved or compartment wagons of the appropriate class. Originality. The scientific novelty of the work is that for the first time, based on selected concepts, a system of modules for the design of passenger wagons for various functional purposes, their definitions and evaluation of the prospects of the proposed modular design systems for passenger wagons. Practical value. Developed systems of modular design of promising passenger sleeping wagons and compartment wagons of the new generation provide a significant increase in their comfort levels, improve the quality and safety of passenger transport, as well as significantly reduce the timing and amount of funding for cars of different classes and purposes, maintenance and repairs during operation.
