2P1-Q11 Analysis of dynamics of air filled play equipment under condition of repetitive impact(Digital Human)

Abstract

Recently, unintentional injuries due to play equipment with air-inflated membrane structure occur frequently as this type of playground is becoming popular. Shock absorption performance of air filled play equipment is intricately changed by repetitive external impact. In this study, the authors developed a femur impact which is used for impact measurement in order to repetitive impact. A finite element model of the play equipment was also developed to conduct basic analysis od dynamics of the equipment.
