智能型刚体转动惯量测试仪的设计

Design of Intelligent Rigid Body Inertia Moment Instrument

介绍了一种测量刚体转动惯量的智能型实验仪器。转动惯量测试仪在转动过程中利用MCS51单片机外部中断和内部定时/计数器的功能,自动记录下每转过π弧度时的次数和时间,并由单片机汇编语言程序计算和显示出刚体的角加速度。经过实验测试表明,该实验仪器不仅提高了测量精度,而且减少了实验过程中许多计算、操作环节。

This paper introduced a kind of intelligent rigid body inertia moment instrument and analyzed experiment principle. With the functions of external interruption and internal timer/counter of MCS51 single chip computer, the circuit and software used to measure an angular acceleration for turns of the rigid body are designed, then the experimental results are given.
