Abstract


Air spring suspension system is high speed train one of the key components of, in other industrial department also have a wide range of application. In its mechanics simulation, because it involves the finite element theory of geometric nonlinearity, material nonlinearity and boundary nonlinear, its calculation work is more complicated and difficult, so, at home and abroad and is not very good solution. This paper first introduced the current widely used nonlinear finite element software ABAQUS to calculate D580 air spring, consider the air spring in different conditions and mechanical properties of high speed passenger air spring to influence the mechanical properties of all kinds of main parameters are discussed in detail. Through the comparison with experimental results can be seen in this paper the calculation method is effective, it can be suitable for other types of air spring mechanics performance analysis, and for the future of the new type of air spring provides theoretical basis for designing.
