A Steam Locomotive Miniature Model Design

This article’s main subjects are the theoretical underpinnings of a steam locomotive’s conceptual layout, engineering design, and calculations, which will be necessary when making a working model of the locomotive. A steam locomotive is a locomotive that uses steam as its power source and steam engines as its engine. The design of the main components of a steam locomotive, including the steam boiler, the steam engine, and the locomotive underframe, has been discussed in this article. To better understand these issues, the article also includes the design of a steam locomotive model created using the CATIA V5 program and the calculation of main components. Calculations of the main parameters of a connecting rod are performed. There are calculated forces efficiency, pressure and power. These parameters are very important for the proper design of the miniature locomotive model. Additionally, the steam boiler is analyzed by means of the finite element method. The analysis has shown that the boiler structure is able to withstand the steam pressure during the locomotive operation.
