英式橄榄球司克兰器的研制与应用

Development and Application of Rugby Scrum Equipment

以解决橄榄球司克兰技术在教学、训练中量化力量、防止颈部损伤及校正技术动作标准等为目的。运用机械工程设计法、力学试验、设计计算和加工制作,研制了用器械替代用人力的司克兰教学训练辅助器材。试验取得了关键技术参数,并对样机进行了实际应用检验。得出橄榄球队员的体重与推顶力具有二者相关关系和推顶力的置信范围,P<0.05;在1-α=95%的条件下,受力置信范围是可信的。验证了橄榄球司克兰推顶力设备具有技术性能可靠性和对提高橄榄球司克兰教学训练质量具有十分良好的效果。

The paper aims to solve problems existing in rugby scrum technology,such as quantizing strength,preventing neck injury,adjusting technical motions according to standard etc.It develops scrum educational and training equipment to replace human power by mechanical engineering designs,mechanic experiments,design calculation and manufacture.The test gives us the crucial technical data and inspects the model machine in the actual application.We can conclude that there is a relation between the weights and ejection force.If the confidence interval is in the range of P0.05,and under the condition of 1-α=95%,then the load-carrying capability range is credible.It verified the reliable performance of the rugby scrum ejection force function and it has a good effect on improving rugby scrum teaching.
