Aluminum honeycomb panel is used as a key lightweight raw material in the airline processing industry. It has also been used on foreign railway cars for a long time. Its main use is equivalent to universal. China has only begun to apply aluminum honeycomb panel in the past two years. The necessary practical effects are limited in its application scope. Understanding of the characteristics and application scope of honeycomb barrier plastics also strengthens learning and strengthens and expands.
In China, the first use of aluminum honeycomb panels was to manufacture the compartment walls of 20a type soft sleeper passenger cars, because at that time the production technology was not grasped in time, and the actual results were not ideal. Therefore, it cannot be applied and promoted on the next 20 passenger cars. At the end of the 20th century, because of the high requirements for light weight of the car during the development and design of high-speed rail trains, aluminum honeycomb panels were first produced on domestic high-speed rail train prototypes to produce bulkheads, cast-in-place panels and door frames for automobile doors. Obtained remarkable results. Then, aluminum honeycomb panels were used on a large scale. At that time, not only were aluminum and aluminum honeycomb panels used for the production of bulkheads, cast-in-place panels, bilge plates of under-vehicle machinery and equipment, and various door frames for automobile doors.
Aluminum honeycomb panels are also used to produce the central air-conditioning duct and the flap cover of the clean air-conditioning unit. Among them, the application of the wall, the cast-in-place plate, the central air-conditioning duct, and the flap cover of the clean air-conditioning unit is more practical. Obviously, it not only greatly eases the quality of related parts and components, maintains the overall light weight of the car, but also improves the precision and quality of parts manufacturing, thereby improving the manufacturing quality of the whole car. However, it is the CRH series of high-speed rail trains that have made groundbreaking progress in the application of aluminum honeycomb panels. With the continuous progress of the domestic production and manufacturing system of CRH series high-speed rail trains in recent years, China can already apply aluminum honeycomb panel forming production and processing technology to produce complex-looking parts and components. To a higher standard.
A real grasp of the characteristics of aluminum honeycomb panels and the design and use of design concepts can deepen the expansion of the scope of aluminum honeycomb panels, and promote the lightening of railway cars.
