双杠测力传感器的研制和应用

<正> 前言在双杠动作的技术分析中,过去多从运动学或运动形态学方面进行阐述,即研究身体在空间的位置(或身体各环节的相对位置)随时间变化的几何性质,而对双杠技术动力学特征的研究,在国内尚很少见。为了更深入地揭示动作技术的内在规律,就必须研究身体运动的变化和作用于身体上的力之间的关系。因此,就需要相应解决测试技术和测试方法的问题。

THE DEVELOPMENT AND APPLICATION OF THE FOVCE-FINDING SENSOR FOR PARALLEL BARS

The development of the force-finding sensor of parallel bars is an atte- mpt to apply"the stress-finding method with electricity" in the analysis of experimental stress to the analysis of the exercises of parallel bars in exercises on apparatus. This article describes, in details, the significance of the development, and the structure, principles, main properties, advantages of the sensor, as well as how to fit and use it. And the article also theoretically alyses the sensor with the results of application. All these play a certain part in making use of the stress-finding method with electricity to study the characteristics of the dynamics in the techniques of parallel bars Also in this article reasonable suggestions of the developmonts of multi dimensional sensor and the telemetering sensor are made.
