KRD300 Moment of Inertia Measurement System

Mass Moment of Inertia (Moment of Inertia) is a measure of an object’s resistance to change in rotation direction. Moment of Inertia has the same relationship to angular acceleration as mass has to linear acceleration.

Moment of inertia measurement system mainly measures the axial and radial moment of inertia. The radial moment of inertia is calculated by measuring the free swing period of the swing system under load and no-load when the specimen installation axle is parallel with the swing axle of the measurement instrument according to the swing measurement principle. As for the specimen that cannot be fixed vertically, the axial moment of inertia is calculated with the measured rolling period of the system when the specimen is made to roll.

Pre-spiral driven by the motor can automatically deflect and release, which is easy and convenient to operate.

The limit mechanism is designed for the pre-spiral and rolling of the motor; when the limit reaches, the motor will automatically stop to protect the device from the damage caused by misoperation, and enhance operational safety.

Moment of inertia measurement system that does not need to be leveled can be installed directly on the ground for easy moving.

The frequency of the measurement system equipped with a rapid-response photoelectric sensor enjoys high measurement accuracy and good repeatability.

Automatic calibration device is specialized to calibrate the system online.

The measurement range is related to the measurement accuracy.

The measurement of radial and axial moments of inertia can be designed as one to occupy less space.

KRD300 series measurement system can measure product of inertia and angle of principle axle of inertia in the slender body.

Air-floating moment of inertia instrument is suitable for the product whose load is less than 500kg; the ratio of maximum moment of inertia to the minimum can be up to 20 when measurement accuracy is 0.1%.
