摘　　要：转轴角加速度是旋转机构转动时的一项重要参数,利用现代科技手段测取各旋转体的角加速度在实践中有着广泛和重要的应用。对角加速度的测量原理、方法进行了研究,寻求了一种高精度连续测量角加速度可行的方法,并对角加速度测量系统的计时环节进行了误差分析。应用了高速、高性能AVR单片机的特有功能:其计数器T/C1特有自动捕获方波信号的上升或下降沿的功能。Shaft angular acceleration is one of the most important parameter to indicate the statue of rotary gears. By means of modern science and technology,angular acceleration is measured and it has wide and important application. The measuring theory and method of angular acceleration is researched. An approach to highly accurate and successive angular acceleration is seeked. However, the time tache＇s error percentage of measurement is analysed. AVR micro -controller with higher speed and excellent performance is applied in this measuring system. Of the most importance,it has unique function which timer/counter 1 can automaticly capture the rising edge or falling edge of the square wave.
