摘　　要：本文依据投掷标枪飞行的初始条件,结合风洞实验所获取的标枪空气动力学特性及标枪的物理特性参数,建立数学模型,用计算机模拟投掷标枪的方法,揭示出投掷新型女子标枪的最佳出手角及迎角,同时指出了影响标枪的升阻比及空气动力力臂值的主要因素.A mathematic model was established based on the initial conditions for the flight of the javelin, the aeromechanic characteristics of the javelin obtained in wind tunnel experiment and the physical parameters of the javelin. Using the computer simulation, the optimum release angle and shot angle of the new model woman javelin were determined. Meanwhile, the main factors affecting the lift-drag ratio and the value of force arm of the javelin were identified.
