摘要
飘球运动是一个各种物理力学综合作用的过程,根据重力、浮力、附加质量力、飞行阻力和玛格纳斯升力等建立动力数学模型。通过分析飘球运动的数学模型,导出飘球轨迹的弯曲程度与球的初速度、角速度以及纵向位移参数关系,解出飘球最佳攻击区间。对大飘移量球参数和最优飘球参数模拟仿真实验。结果发现:大飘移量球在球落地时其飘移积累量达到最大,接球方最难以应付;最优发球参数在v=16.7 m/s、θ=23.9°时球最具威胁性和攻击力。
Floating ball movement is a comprehensive effect of various physical mechanics.According to the process of gravity,buoyancy,additional quality force,flight resistance and margate lift kenaz,a mathematical model was established.By analyzing the mathematical model of floating ball movement,the floating ball trajectory was derived from the ball early bending degree and velocity,angular velocity longitudinal displacement parameter relation.Moreover,the best attacking interval was worked out.The simulation results of big moves quantity ball parameters and optimal floating ball parameters were found: when the ball with big shift quantity landed,its shift accumulation quantity is the largest,and the ball is the most difficult to cope with;When the optimal parameters is v=16.7 m/s and θ=23.9°,the ball is most threatening and destructive.
