构件转动惯量的测试方法初探

本文对复摆作微幅摆动进行了分析，根据其运动规律，采用刀口支承和轴颈支承两种方法，对形状不规则构件或较大构件的转动惯量如何测试进行了探索，从理论上对两种测试方法要点进行了分析阐述．该测试方法具有简单、准确、省时、使用方便、易掌握的特点，特别用于现场测试。

Research on the Testing Method of Component Rotational Inertia

In this paper, analysis on the minute amplitude of compound pendulum is conducted, According to the law of its moving, research on the test of rotational inertia of irregular component or bigger component is conducted by the means of edge-support and axle neck support. For these two methods,their main points are discussed from theoretical perspective. This method is simple, accurate, time-saving, easy-to-be-used and mastered, and thus is especially applied to the spot test.
