Application of Honeycomb Aluminum Plate in Transportation

随着铁道车辆的发展，提高车辆设计和工艺水平已受到国内外的关注。根据我国客车结构设计情况看，降低自重，改进防寒、隔热性能及提高防火能力都是迫切需要解决的问题，为了减轻车体重量简化结构,To improve efficiency, the lightness of the internal equipment of passenger cars has been paid more and more attention in foreign countries, and the use of interior wall panels, partition panels, flat roof panels, door panels, etc.Honeycomb aluminum plateObvious results have been achieved. This new technology changes the technical performance of the parts, prolongs the service life, and reduces the maintenance and repair work of the vehicle. At the same time, it gives people a sense of comfort and improves the aesthetics of the guest room. Changchun Bus Factory adopted this honeycomb aluminum plate structure in the new bus, and developed the hot pressing process and the corresponding large-format hot pressing machine, and achieved certain economic benefits.

The so-called aluminum honeycomb composite plate structure is an aluminum honeycomb sandwiched between two layers of aluminum plates, and the outer surface is attached to a polyamine plate. This new structure, in addition to light weight, has high rigidity and longitudinal stability, and has good heat insulation, sound insulation and electrical insulation. It not only saves wood, but also improves fire performance. Honeycomb aluminum plate structure and its hot pressing process, large format hot press, etc., it is the first time in the application of railway passenger cars, is a new technology and new process. The honeycomb aluminum sheet formed by pressing does not need any other processing and can be directly loaded for use.

In recent years, my country\'s transportation industry has continued to advance by leaps and bounds, and railway passenger cars have been continuously updated. The traditional passenger car floor is an ordinary wooden floor covered with iron sheet, which has the disadvantages of large volume, heavy quality and high cost. Because urban rail vehicles have the characteristics of light axle weight, frequent acceleration and deceleration and overload operation, the steel structure of the car body is required to be as light as possible under the requirements of strength and stiffness, so that light structural materials and low-density materials must be used in the design of urban rail vehicles, and honeycomb aluminum plates are used.
