High Precision Measurement of Moment of Inertia Based on Compound Pendulum
A new method and equipment based on compound pendulum was designed for measuring moment of inertia (MOI). The measurement principle of the system, being quite different from the traditional method which records the swing period of the compound pendulum, records the Angle-time curve and conducts a series of computation featuring phase-plane to obtain the MOI of the object being measured. The proposed method could effectively eliminate the friction moments influence on the measurement results and enhance the precision up to 0.12％. The method is suitable for the heavy and large-scale objects, especially those with large length/diameter ratio.
