background: in ordinary life, we as students, always full of vitality, love sports, then, sports equipment has become the essential things in life, and sports shoes, not only is the sports requisites, become more and more indispensable in life, learning will spare parts, related to the quality of sports shoes and we quality of life, so the study of sports shoes for shock absorption technology is necessary.

Abstract: in the production of Nike Jordan sports shoes, air cushion used to achieve damping, energy return, decoration is to practice It is quite common for the world in the production of sports shoes, the use of sports shoes production in China are also very common cushion. But because the deep study of various manufacturers lack of function and performance of the sports shoes cushion, unable to function, performance of air cushion and products meet the requirements, and even to bring greater harm in motion by use of because of air. Neglect the study of air cushion not only affects the sports shoes of the added value of ascension, bring customer inconvenience; and the limit of China's footwear industry depth development, affecting the status of China's footwear industry in the world, obstacles to enter the high-end products.

keyword: sports shoes; air; damping

idea: for shock absorption technology air cushion, you can start from the insole structure, we can use a high toughness material, which has the characteristics of softness, elasticity, not easy to deformation, let insole heel bubble type, and with the function of ventilation, the insole can not only shock absorption, deodorization, can heat dissipation.

the following several commonly used air cushion are summarized:

according to the classification of material

materials for air cushion performance is great. The most commonly used air cushion materials with polyurethane (PU), polyvinyl chloride (PVC) thermoplastic polyurethane (TPU) etc.. The following paper cushion and polyurethane polyurethane insole molding cushion, PVC soft cushion and cushion, hard PVC thermoplastic polyurethane tube air cushion and thermoplastic polyurethane filling cushion and use advantages and performance.

The comprehensive performance of

polyurethane material is very good. Not only is its high strength, high elasticity, high compressive strength, tensile properties, wear resistance, the oxygen and ozone resistance, solvent (such as non polarity solvent hexane, heptane, paraffin oil, for Nike Requin Homme polar solvent polyurethane almost no role, even in high temperature conditions, non swelling polyurethane in polar solvents also Nike Air Max small), and light weight, is very useful for the lightweight design of shoes. But the polyurethane has poor water Air Jordan resistance, high internal heat.
