Proposal of simple calculation formula of additional load of air play equipment

Abstract

Accidents caused by strong winds during outdoor use of air playground equipment, which are often seen in amusement parks, event venues, indoor play facilities, etc., have occurred in recent years. Since the weight of the air playground equipment is light and easily blown away by the wind, it is necessary to fix it with a pile or weight when installing.Currently, in Japan, Japan Inflatable Products Safety Association(JIPSA) has established a provision for safety management, but has not yet reduced the damage. In this study, we proposed a calculation formula for calculating the degree to which additional load (sandbag, weight such as polytanks, and pegs) to be installed auxiliary in the air playground equipment is necessary. In addition, the pulling test was also performed to examine the strength of the batting pile required for the calculation formula.
