Study on the Application of Carbon Fiber Composite Materials in High-Speed Trains

Abstract

The new carbon fiber composite materials trains hood is designed with vacuum infusion molding process characteristics and performance of existing trains hood according to the characteristics of the high specific strength and stiffness of the carbon fiber composite materials. According to the requirements of referring to the IEC61373-1999[Railway Rolling Stock Equipment Shock and Vibration Testing Standards] and GB/T3317-2006[Electric Locomotive General Technical Conditions], the strength and deformation of the trains hood is calculated and analyzed on the conditions of the impaction, air movement load case and the end compression. The test result shows that the mechanical properties of the structure meets the requirements in the 500km/h high-speed test train.
