力学原理与竞技高跷创新设计

The Princple of Mechanics and the Innovative Design of Stilts for Competition

对竞技高跷造形结构的力学功能、制跷材料的力学特性及人跷系统的整合性进行了研究 .结果表明 :高跷踏镫的形状、踏镫与撑杆的连接方式、撑杆的高度、手柄与撑杆的连接方式及跷底防滑钉都会影响高跷的力学功能 ;高跷的不同部位应选择不同刚度的材料 ,适宜的踏蹬加垫层能起到缓冲和二次利用能量的作用 ,各部位的材料韧度越大越好 ;人跷系统的整合性影响运动成绩 .

According to the studies on the mechanical functions of stilts' shape and structure,on the mechanical characteristics of materials used for stilts,and on the conformity of athletes and stilts system,the results indicate that these factors have influences on stilts' mechanical fuctions,including the shape of stilts' footboards,the way of combining the footboards with the stay bars,the stay bars' height,the way of combining the handles with the stay bars,and the skid nails.The results also indicate that appropriate materials used for footboards have a cushioning effect,and it can also make second use of energy.Finally,the results indicate that the conformity of athletes and stilts system can influence sportsman's achievments.So the author proposes a theory of innovative stilts design for competition,which can embody athletes' individual characters.
