Problems solved by technology

[0002] Existing rotating body pole moment of inertia tester, such as: desktop swinging moment of inertia tester, horizontal pole moment of inertia tester, in the test process, the rotating body of the object to be tested is fixed in the spring swing system, and each measurement requires Clamping and aligning the centerline not only make the measurement process cumbersome, but also cause the inconsistency between the actual rotary axis and the theoretical rotary axis due to the clamping and centerline alignment, and the repeatability of the system is poor, which affects the measurement accuracy of the system
In addition, different types of fixtures are required for different shapes of measured objects, which is very uneconomical
