Lightweight Design concept Aluminum Alloy car body parts of Rail Transit

SMM News: with the continuous development of rail transit industry in China, rail transit has become the main mode of transportation for people to travel every day. Car body parts are one of the most important components of rail transit vehicles, which are mainly composed of underframe, left and right side walls, front and rear end walls and ceiling six modules. The aluminum alloy car body parts absorb the lightweight design concept, adopt the design scheme of thin-walled hollow aluminum alloy profiles, combined with the integral welding process, and better consider the relationship between strength and stiffness.

Compared with the traditional carbon steel and stainless steel car body, the aluminum alloy car body has obvious advantages in weight. The aluminum alloy material density is only 1 × 3 of that of steel, and the weight of each car can be reduced by about 1 ton, which can obviously reduce the energy consumption. 10 to 15000 kilowatt hours of electricity can be saved every year, so as to improve the vehicle operation capacity. In terms of anticorrosion and corrosion resistance, aluminum alloy itself is an environmentally friendly and anticorrosive material, and it can be recycled, and a dense oxide film can be formed on its surface in the natural state, even if the anticorrosion protection on the surface of the car body is in a state of shedding or damage, it can also ensure the corrosion resistance of the car body, and the service life of the car body can reach more than 30 years. In terms of air tightness and appearance, the aluminum alloy car body is an integral welded structure, its air tightness is better, and its appearance is more beautiful after spray painting on the same surface. Due to the outstanding advantages of aluminum alloy car body structure, the consumption of rail transit car body products at home and abroad is increasing year by year.

Shandong Novik lightweight equipment Co., Ltd., a subsidiary of Jungle Aluminum, is mainly engaged in the welding and processing of aluminum alloy car body parts of high-speed rail transit, subway and other large-scale rail transit, with a number of international advanced modern automatic welding and CNC processing production lines, with an annual production capacity of 3000 car body modules. Among them, relying on the high-standard industrial profiles produced by jungle aluminum as raw materials, the extension of aluminum alloy deep processing industry chain has been realized. Using the international rail vehicle welding standard EN 15085-2 CL1, it is a strategic cooperation enterprise of famous rail vehicle transportation companies such as China Railway Corporation, Siemens in Germany, Alstom in France and so on.
