Experimental Study of Shoe Cushioning System of Shock Absorption Using Fluid Damper with Nano Particles

나노입자 유체댐퍼를 이용한 보행 충격 완화 장치의 충격 흡수에 대한 실험적 연구

This study developed and evaluated a shoe cushioning system to reduce impact force patterns during running. The shoe cushioning system is composed with a poly urethane pocket, which contains water and porous grains to absorb the force against the weight inside the pocket. Load-displacement curves for the shoe cushioning system were obtained from an instrumented testing machine and the results were compared with various pockets that have air, water or grains. Mechanical testings showed that the pocket with 5 g particles was the best for the shoe cushioning system. This founding will be helpful to designing the shoe.
