https://doi.org/10.46973/0201-727X_2025_3_64
Abstract
The paper considers technical solutions obtained by step-by-step optimization of enclosing structures of thermos wagons. The main goal of optimization is to reduce material consumption without increasing the overall heat transfer coefficient.
A key aspect of the research is the developed step-by-step optimization algorithm based on a combination of analytical calculations and the finite element method. This made it possible to evaluate the thermal engineering properties of the structure, eliminating thermal insulation in areas that do not affect the overall coefficient of thermal conductivity of the thermos car.
The results of the work are of practical importance for wagon-building enterprises, as they make it possible to reduce the cost of manufacturing thermos wagons, reduce the labor intensity of production and improve their technical and economic performance.
