摘要
分别对“同心鼓”运动中排球掉落弹起过程、人对鼓作用力、特定力对鼓的作用做受力分析,采用相应的物理量、物理运动状态,建立数学模型研究“同心鼓”相应的数学问题。通过物理计算,建立了用力大小、发力时机与倾斜角的关系模型。现实情况下,人不可能准确地把握时机、力度,所以调整策略效果不能达到理想效果,通过分析调整策略效果,使得模型属于合理范围内。
We do force analysis of the volleyball drop and bounce course,acting force of men and specific force on drum during“concentric drums”movement.Through adopting corresponding physical quantity and physical motion status,the corresponding mathematics problems of“CONCENTRIC DRUMS”are researched based on the establishment of mathematics model.Through physics calculation,the relation model of strength,power generation and angel of inclination is established.In actual situation,men can’t accurately grasp time and force,so adjustment strategy effect isn’t good.We should analyze strategy effect to make model be in the reasonable scope.
