パラアイスホッケー用スレッジにおけるフレーム軽量化のための形状設計

抄録

Para ice hockey is an adaptive form of ice hockey used for athletes who have a disability which could be from limb loss, spinal cord injury, or a condition such as cerebral palsy. Athletes use a special sled called ‘a sledge’ to play para ice hockey. Because para ice hockey is a very physical sport, a sledge needs high strength and stiffness. Most of Japanese athletes in para ice hockey use foreign sledges made of Al alloy. Their sledge is so heavy and bad handling for Japanese athletes. Repairing damaged sledge takes a lot of time and money because of transport to foreign manufacturing. Thus, Japanese athletes need a domestic sledge with lightweight, high-strength, high rigidity. So, focusing on Mg alloy which has lower density than Al alloy, a domestic sledge made of Mg alloy was prototyped. The purpose of this study is to further reduce the weight of the prototype sledge using optimization analysis.
