摘要
铅球运动员投掷的最佳路径分析可以全面提高铅球运动员的比赛成绩。对于铅球投掷最佳路径的检测,需要对铅球投掷过程中某一时刻的垂直速度和水平速度进行计算,并且要充分考虑到阻力因素,并且要组建铅球投掷最佳路径的计算方程,完成最佳路径规划。传统的计算方法是根据应力值为训练样本提供初始的数据参数,给出最佳的应力参数,但并不能根据数据建立计算方程,这样不能精确计算结果。基于力学分析法的最佳路径检测,是将物理力学与运动学结合在一起,计算出影响铅球最佳投掷的因素。组建最佳路径计算模型,能够计算出水平速度和垂直速度及阻力,计算出最佳路径。通过实验调取的数据说明力学分析算法可以提高计算精度,提高训练的精准度,提高效率。
The analysis of the best throwing path of shot putters can comprehensively improve the performance of shot putters.For the detection of the best path of shot put,it is necessary to calculate the vertical speed and horizontal speed at a certain time in the shot put process,and to take full account of the resistance factor,and to establish the calculation equation of the best path of shot put,to complete the optimal path planning.The traditional calculation method is to provide the initial data parameters according to the stress values of training samples and give the best stress parameters,but it can not establish the calculation equation based on the data,so it can not accurately calculate the results.The best path detection based on mechanical analysis is to combine physical mechanics and kinematics to calculate the factors affecting the best shot put.The best path calculation model can calculate horizontal and vertical velocity and resistance,and calculate the best path.The experimental data show that the mechanical analysis algorithm can improve the calculation accuracy,training accuracy and efficiency.
