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 strength and stiffness. Foreign-made sledge is heavy and bad handling for Japanese athletes so there is a necessity of their weight saving. Therefore, Mg alloy sledge was manufactured because of weight saving. However, there were some problems about strength and stiffness for Mg alloy sledge. The purpose of this study is to evaluate strength of frame shape for Mg alloy sledge using finite element (FE) analysis. Based on the drawing, CAD models of Mg alloy prototype sledge were created, and their FE models were constructed. From FEA result on frontal impact, several high stress values were found in the sledge frame.
