Aluminium alloys are being used more often as a result of industry demands for strong, lightweight materials.
The results of these tests help determine how resistant a material is to cavitation and direct the development of materials for use in cavitation-prone environments.

The accuracy of design and manufacture is the key of model test.For a arch ridge with curved beam and skewed arch, the model test based on the similarity theory is analysized in detail including selecting materials, designing the size of section and calculating the geometrical parameters and so on, and the simulation reults between model and prototype are evaluated.Meanwhile some key technologies and valuable matters for design of aerodynamic model are presented,which provides an important reference value for model design of bridge structures.
