摘 要本文主要研究对于标枪最终投掷距离的初始的条件的影响，例如出手的角度出手的速度等。而空气动力学的研究表明，单纯增加标枪投掷的初始速度，获得的成效并不能令人满意。这时，就引入了初始攻角这个概念。同时，还要考虑到在标枪的飞行过程中所受到的空气阻力。对这些回产生影响的因素之间的关系进行简化，使用这些参数建立起标枪的飞行轨迹模型。最后，对于这些影响最终投掷距离的参数的相对重要性进行合理的总结和分析。最终得出，标枪初始的速度和出手的角度两种参数的影响较大，其中在出手角度为 41°时达到最大值，而初始攻角的影响相对较小，在 18°时达到最大值。其他的参数造成的影响几乎可以忽略不计。关键词 标枪 参数 空气动力学 相对重要性AbstractThe article mainly studies the influence of the initial conditions on the final throw distance of Javelin, such as the angle of release and the speed of release. But research at the aerodynamics suggests that simply increasing the initial speed of javelin throwing is not as effective. At this point, the concept of the initial angle of attack is introduced. At virtually the same moment, during the flight of the Javelin, the air resistance must be taken into account. Between these factors, the relationship is simplified, and the flight trajectory model of Javelin is established by using those variable. Finally, the relative importance of these parameters which influence the final throw distance is reasonably summarized and analyzed. The final results lay out that the initial velocity and the angle of the Javelin throw have a great influence on the javelin throw, and the maximum value is reached when the angle of the javelin throw is 41, while the effect of the initial angle of attack is relatively small, reaching the maximum value at 18. The impact of the other parameters is almost negligible.Keywords Javelin Parameters aerodynamics Relative importance目 录摘 要.......
