The development of the transport industry is relatively fast, such as the railway now replace Pood from the traditional to the high-speed rail motor car. In traditional carriage, are generally wooden floor, he volume is relatively large, and the quality and weight, the key is the high cost, which is also his shortcomings. But now into a rail car quality is relatively light, frequent acceleration and deceleration can also be overloaded to run.
In fact, this also requires our car steel structure to meet the strength and stiffness, of course, this also requires us into a rail car when it is best to design a lightweight structure and relatively low density material, and aluminum honeycombthe board is a good choice. Jiangsu Province Ceramics Research, aluminum honeycomb panels his structure is very reasonable stiffness and strength, you can also further improve on the basis of criteria, so good in light rail, subway, buses and other applications.
Aluminum honeycomb panels on both sides of the panel are high-strength aluminum, which is hexagonal aluminum honeycomb Jiangsu Ceramics Research Institute, can be used as a sandwich core board. Even if it is to withstand the upward pressure, they will mutual restraint, the dense cellular seems to be a lot of unskilled laborer-beam, able to withstand a wide range of pressure, let it even by force, which would also ensure good flatness.(picture/text http://www.jiangsuceramics.com/)
