Abstract

Abstract. This study investigates the thermal performance of passenger car body enclosuresusing a controlled test chamber. Due to the relatively high heat transfer coefficient of existing designs,the need for improved thermal insulation has been identified. Modern insulation materials with lowthermal conductivity were analyzed, and four prototype samples were tested. The best results wereobtained from samples using corundum and polyurethane foam. These materials also provideeffective corrosion protection. To ensure measurement accuracy, the test chamber was calibrated.The study presents a validated methodology for selecting thermal insulation materials for railwayrolling stock.
