120 km aluminum truck multi-purpose gondola car design
Abstract： At present, the railway transport capacity can’t meet the requirements of capacity,
develop the overloaded unit train is one of the important measures to solve the current capacity
is insufficient. Aluminum alloy gondola car design will be as far as possible to overcome the
problems existing in the existing gondola car use, it will extend the service life of car body and
factory repair cycle, reducing the workload of completed on factory. The multi-purpose gondola
car adapt to general cargo transportation, and can meet the requirements of overloading,
combined train operation, give full play to the potential ability of the multi-purpose gondola car,
has very important practical significance. This topic will use aluminum alloy to gondola car
design, realize the lightweight car body design, it will not only reduce the body weight, and in
the case of ensure enough strength can realize heavy tasks. Vehicle lightweighting design
usually by the original vehicle on the basis of the improved structure, choose change the
material to achieve a goal. Improved structure is an important developing direction of
lightweight design should be throughout the whole process. But light is not aluminum alloy,steel structure rationalization of car also has an obvious effect of lightweight.
Key words: Gondola car； Lightweight design；Aluminum alloy； The optimization design
