【摘要】：铅球运动员投掷时对于最佳路径的检测,可有效提高铅球运动员的比赛成绩。对铅球的投掷路径的检测,需要根据某一瞬间水平和竖直方向的速度分量参数,组建铅球投掷时最佳路径检测微分方程,完成路径的检测。传统方法根据正应力值为训练样本给出铅球初始运动的特征参数,给出铅球投掷时最佳应力参数,但无法组建路径检测微分方程,导致检测结果不准确。提出基于力学分析的铅球投掷时最佳路径检测方法。融合于生物力学原理计算出影响铅球路径的因素,组建铅球射程方程,获取铅球飞行距离的最大值,组建最佳路径变化规律模型,计算出铅球在投掷后的运动过程某一瞬间水平和竖直方向的速度分量及其阻力,组建铅球投掷时最佳路径检测微分方程,利用该方程检测铅球投掷时最佳路径。仿真结果表明,所提方法计算精度高,可以为教练员科学训练实践提供理论依据。
[Abstract]:The detection of the best path of shot put players can effectively improve the performance of shot put players. In order to detect the throwing path of shot put, it is necessary to set up the differential equation for detecting the optimal path of shot put according to the velocity component parameters of the level and vertical direction of a given moment, and to complete the detection of the path. The traditional method gives the characteristic parameters of the initial motion of shot according to the normal stress value of training sample, and gives the best stress parameter when shot is thrown, but it can not set up the differential equation of path detection, which leads to the inaccurate detection result. A method for detecting the optimal path of shot throw based on mechanical analysis is proposed. Combined with biomechanical principle, the factors affecting shot path are calculated, the shot range equation is established, the maximum flying distance of shot is obtained, and the law model of optimal path change is established. The velocity components and their resistance in the horizontal and vertical direction during the course of shot throw are calculated, and the differential equation for detecting the best path of shot throw is set up, which is used to detect the best path in shot throwing. The simulation results show that the proposed method has high accuracy and can provide theoretical basis for the scientific training practice of coaches.
