AI Technical Summary

⚠Technical Problem

The existing bogie antenna mounting beams are mainly metal welded structures, which have problems such as stress concentration at the welds, easy cracking, complex structure and heavy weight. Existing composite material replacements have not effectively solved the problems of overall lightweighting and structural simplification.

⚗Method used

Composite materials are used to make the bogie antenna mounting beam, and the horizontal beam, mounting bracket and antenna mounting base are integrally molded, eliminating welds. The manufacturing process uses a combination of molding and bag pressing to achieve integral molding and internal hollow structure. The combination of carbon fiber and glass fiber woven fabric is used to improve impact resistance and fatigue resistance.

🎯Benefits of technology

This resulted in improved overall stiffness, reduced weight, fewer welds, simpler structure, and enhanced impact and fatigue resistance of the bogie antenna mounting beam.

Abstract

The application discloses a composite bogie antenna mounting beam and a manufacturing method, and relates to the technical field of railway vehicles. The application solves the problems of complex structure, large weight and easy cracking of the existing antenna mounting beam, improves the overall rigidity and reduces the overall weight. The specific scheme is as follows: the beam, the mounting bracket and the antenna mounting seat are made of composite materials, are integrally formed, the mounting bracket is fixedly arranged at the two ends of the horizontal beam, the antenna mounting seat is fixedly arranged at the middle position of the horizontal beam, at least one mounting hole and one process hole are arranged on the mounting bracket and the antenna mounting seat, and the horizontal beam, the mounting bracket and the antenna mounting seat are hollow and communicated.
