| 摘 要： | 本文介绍了投掷运动选材与训练测试系统的设计思想和工作原理。该系统由投掷物出手速度测试仪和最大挥臂加速度测试仪组成。前者通过由光敏元件组成的光敏列阵传感系统,将投掷物出手时的飞行参数转换成电讯量;后者应用半导体加速度传感器将挥臂过程中的加速度变成电讯量。这些电讯量经过放大后.输入计算机处理,给出出手速度 v_0和最大加速度α_(max)值,并由打印机打出最终结果。该系统自动化程度高,能快速自动测量与记录。

| Abstract: | The design idea and working principle of the measuring system for selecting and exer- cising of throwing sport athletes are introduced in this paper.It is composed of the meas- uring instrument for the throwing speed of the thrown object and the measuring instrument for the maximum acceleration of wielding arm.The former is:when an objcet leaves the hand,the flying parameter of it is transferred to electrical quantity by the column light scn- sitive transducer system,which makes up of light sensor.The latter is:the acceleration in the wielding process is transferred to electrical quantity by the semiconductor of acceler- ating sensor.This electrical quantity is amplified and then transported to computer to be deal with.The computer gives out the throwing speed v_0 and the maximum acceleration a_(max) and the terminal results are printed by a printer.This system is highly automatic and, can be used to quicken automatic measure and record. |
