Study on the Heat Insulation Performance of EMU Structure

Abstract

In recent years, with the improvement of the EMU performance, the EMU structure and material also had a series of changes. These changes can produce certain effect on the train body heat insulation performance. Heat insulation performance is the main factor of structure heat transfer, the motor train unit section heat insulation performance, and the factor for analyzing motor train unit operation energy consumption, which is of great significance on determining its air-conditioning load, avoiding the bad working environment (wall condensation and local high temperature) appear, and maintain the car comfortable thermal environment. This paper studies the practical operation heat insulation performance and studies a new generation of high speed EMU thermal performance design provide theoretical guidance and practical tool, which integrated by means of the theoretical analysis, numerical simulation, and experimental test methods, through the heat insulation performance of the EMU structure calculation and analysis.
