转动惯量的智能测试初探

利用传统的三线摆测试转动惯量至今大多用秒表计时、人工计算周期数的方法.这种方法计时精度低,为了减少误差,本文提出的利用单片机测试转动惯量设计方案,选择ATMEL公司生产的AT89C52单片机芯片,具有计时和计数双重功能,较之传统的测试,既方便,又省时,具有精确、高效能等特点.

An Introductory Research on Intelligent Test of Rotary Inertia

So far,most often people traditionally use a stopwatch to time and calculate the periods by hand when testing the rotary inertia by using three –line pendulum.That method produces low precision in timing.To reduce errors,this paper suggests to apply a singlechip to the test.The application of SCM（A789C52） produced in ATMEL,which has twofold functions of timing and counting,makes the test more convenient,more time –saving,more accurate and more efficient.
