摘要
依据流体力学的基本原理,分析了“香蕉”球形成的必要条件,根据实际情况的简化建立了香蕉球的动力学模型,由质心运动定理得出了动力学方程,在二级近似下求出了运动学方程,并且通过举例计算了几种情况下的横向位移.
Essential condition of banana kick is analyzed by fundamentals of fluid mechanics. Dynamics model of banana kick is found according to simplify from the actual situation. Dynamics equation is obtained from motion theorem of mass center. Kinematics equation is obtained on two stages approximate. Crosswise displacement is counted by giving an example.
