Application of Aluminum Honeycomb Panel in Railway

aluminum honeycomb panel作为重要的轻量化材料广泛应用于航空制造业，在国外的铁道车辆上也早有应用，其用途相当广泛，国内仅在最近几年才开始使用aluminum honeycomb panel，虽然取得了一定的效果，其应用范围还很有限，对蜂窝夹层材料的特性与应用范围的认识还有待于进一步加强与扩大。

在国内，aluminum honeycomb panelThe earliest application was to manufacture the compartment wall of 25A soft sleeper bus. Due to the lack of mastery of manufacturing technology at that time, the application effect was not very ideal. Therefore, it failed to continue to promote the application on the subsequent 25 type passenger cars. At the end of the 20th century, due to the high requirements for lightweight vehicles in the development process of EMU, aluminum honeycomb panels were first used to manufacture partitions, flat roof panels and door panels on domestic EMU prototypes, and good results were achieved. Subsequently, aluminum honeycomb panels were applied on a large area. At that time, aluminum honeycomb panels were not only used to manufacture partitions, flat roof panels, underfloor equipment compartments and various door panels.

还用aluminum honeycomb panelThe air conditioning duct and air conditioning unit guide cover are manufactured, among which the wall, flat top plate, air conditioning duct and air conditioning unit guide cover have the most significant application effect, which not only greatly reduces the quality of related parts and realizes the overall lightweight of the vehicle, but also improves the manufacturing precision and quality of parts, thus improving the manufacturing quality of the whole vehicle. However, the real breakthrough in the application of aluminum honeycomb panels is the CRH series EMU. With the continuous deepening of the localization process of CRH series EMU in recent years, the domestic has been able to use aluminum honeycomb panel molding processing technology to manufacture parts with complex shapes, and has reached a high level in the field of aluminum honeycomb panel molding manufacturing and application.

真正掌握aluminum honeycomb panelThe characteristics and application design methods can further expand the application range of aluminum honeycomb panels and promote the further lightweight of railway vehicles.
