测量转动惯量的新装置

Design of a New Equipment to Measure Moment of Inertia

本文介绍了一种测量转动惯量的新装置。该装置用齿轮将圆周等分,通过提高数据采集密度,来提高测量精度。而对于采集到的大量数据点,用MATLAB软件处理,准确、方便。与目前其他测量转动惯量的方法相比,能达到较高的测量精度。

This article mainly introduces a new equipment to measure moment of inertia.We divide the circle equally to improve the gather-data density in use of a gear wheel in the equipment.Then the measure precision is improved.And we use the software of MATLAB to deal with the large amount of data-points collected.So it seems nice and convenient.Compared with other methods today,it is more precise.
