Abstract:
Objective The combined entropy weight technique for order preference by similarity to an ideal solution(TOPSIS)and rank sum ratio(RSR)methods were utilized to rate the protective performance of ice hockey helmets,and the effectiveness and influencing factors of the rating system,as well as the relationship between protective performance and purchase price were explored.Methods The linear acceleration data during impact drops of twenty-four ice hockey helmets were collected using a uniaxial accelerometer in a collision test machine after low and ambient temperature treatments.The protective performance of ice hockey helmets was rated using the STAR model combined with the entropy weight TOPSIS and RSR methods.One-way ANOVA or the Kruskal-Wallis H test was employed to assess the differences in protective performance among helmets across different grade groups.The correlation between different indicators was analyzed by Pearson's correlation coefficient.Results The comprehensive protective performance ratings of the CCM TACKS 310,IBX,BAUD,and WARRIORS COVERT RS PRO helmets were classified as poor,whereas the BAUER REAKT 150,HYPERLITE,and REAKT 200 helmets were rated as excellent.The remaining helmets were rated as moderate.There was a moderate to high positive correlation between the ambient temperature STAR(A)and Rowson's STAR values,the comprehensive Ti and low temperature Ti,the comprehensive T,and ambient temperature Ti(P＜0.05).The comprehensive Ti satisfied the homogeneity of variance(P＞0.05)and exhibited significant differences among groups(P＜0.05).Significant differences were found in the low temperature indicators among different groups(P＜0.05),and their weight coefficients ranked among the top three.The ambient temperature indicators were not affected by the protective performance grade(P＞0.05).A weak positive correlation existed between the comprehensive Ti and purchase price(P＜0.05).Conclusions According to the energy absorption test protocol,the combined entropy weight TOPSIS and RSR methods can efficiently rate the comprehensive protective performance of ice hockey helmets.The effectiveness of using low temperature indicators for the comprehensive evaluation and rating of ice hockey helmet protective performance is superior to that of ambient temperature indicators and purchase price.Consumers are advised not to use price as a criterion for evaluating the comprehensive protective performance of ice hockey helmets.
