【摘要】：对篮球运动员投球目标技术优化培训,可提高篮球运动的比赛成绩。进行投球培训时,应将篮球运动员投球过程中应力、应变变化特性进行分析作为培洲指导的基础,但是传统方法通过分析不同的边界条件对股篮球运动员投球目标技术培训的最大影响因素完成培训,但是不能准确分析篮球运动员投球过程中应力、应变变化特性,导致投球技术培训达不到效果。提出一种基于有限元的篮球运动员投球目标技术优化培训方法。上述模型先利用Mimics和Ansys软件组建人体股骨应力分布模型,在上述基础上约束地面刚体,对模型施加2M\S的速度载荷,得到篮球运动员投球过程中应力、应变变化特性,对人体股骨上段内侧皮质和外侧皮质间中点进行应力计算,并以计算的结果为依据对人体股骨头、骨小梁进行循环压缩试验,分析不同受力方向下股骨头骨小梁的骨体积分数,骨小梁平均厚度,以及弹性模量循环次数等力学指标,依据上述力学指标调整投球的姿势,完成篮球运动员投球目标技术优化培训。仿真结果表明,所提模型为篮球运动员投球目标技术的提高提供了有效的依据。
[Abstract]:The optimization training of basketball players' pitching target technology can improve the basketball performance. In the course of pitching training, the variation characteristics of stress and strain in the course of throwing basketball players should be analyzed as the basis of the guidance of Peizhou. However, the traditional method can not accurately analyze the characteristics of stress and strain changes in basketball players' pitching process by analyzing the biggest influence factors of different boundary conditions on the training of basketball players' pitching target technology, but the traditional method can not accurately analyze the characteristics of stress and strain in basketball players' pitching process. Result in pitching technical training can not achieve results. This paper presents an optimization training method for basketball players' pitching target technology based on finite element method. Firstly, the stress distribution model of human femur was established by using mimics and Ansys software. On the above basis, the rigid body on the ground was restrained, and the velocity load of 2m\ S was applied to the model, and the variation characteristics of stress and strain in the course of basketball throwing were obtained. The stress of the medial and lateral medial cortex of human femur was calculated, and the bone volume fraction of the trabecular bone of the femoral head under different directions was analyzed according to the results of the stress calculation, and the cyclic compression tests of the femoral head and trabecula were carried out on the basis of the calculated results. The average thickness of trabeculae and the cycle times of elastic modulus were used to adjust the position of pitching according to the above mechanical indexes and to complete the optimization training of basketball players' pitching target technology. The simulation results show that the proposed model provides an effective basis for basketball players to improve the goal technology.
