Research on Compression and Rebounding of the Zoom Air in Sport-Shoes
Abstract:
Today, the zoom air was widely used in top grade sport-shoes. Firstly, the function of zoom air, including shock absorption, energy return, light quantization and ornament results were introduced. Secondly, the problem of using the zoom air nowadays was brought forward, through testing the compression and rebounding of the zoom air in sport-shoes, the shock absorption and the energy return of it were researched. The factors of influencing the compression and rebounding of the zoom air were discussed from speed of the athletics and the aging of the zoom air. The speed had effect on the shock absorption performance and energy return performance. The faster the speed was, the smaller the protection the zoom air could offer and the energy feedback were. Ageing would not make the material of the zoom air produce essential change, but may cause the reduction of the gas in the zoom air. All performances of the zoom air were improved after ageing, which means the zoom air in the market was not optimum at present, all this contributed to the lack of united standard. Finally, the method of testing and the standard of evaluation were put forward, which did some early work for the standard of zoom air in producing and testing.
