Description
Technical field
The utility model relates to moment of inertia is carried out technical field of measuring, is specifically related to a kind of servicing unit of rotation inerttia.
Background technology
The moment of inertia size has characterized the complexity that the Rigid Body in Rotation With state changes, and its value depends on the position of shape, mass distribution and the rotating shaft of object.In engineering practice, for complex-shaped and non-uniform mass rigid body, be difficult to calculate moment of inertia by theory, adopt experimental technique to measure usually.Three string pendulum methods become a kind of common method that measures moment of inertia because it has that equipment is simple, easy to operate, precision is than advantages such as height.
As shown in Figure 1, its measuring principle is: the phase countershaft of measured object is overlapped with the balance revolving shaft, make the initial torsion angle (just approximately linear vibration of twisting vibration this moment) of balance deflection one small (usually less than 5 °), naturally discharge then, balance produces periodically twisting vibration, and the moment of inertia of object is relevant on its cycle and the balance; According to equivalence principle as can be known, when the weight of object on A, the B balance, pendulum length equate fully, if both twisting vibration cycles are also identical, can think that then moment of inertia equates.Therefore by adjusting the cylindrical interval S of homogeneous that symmetry is placed on the B balance, can obtain different moment of inertia (can calculate by theory), make the rotation period unanimity of A, B balance, thereby obtain the moment of inertia of non-rotational symmetry on the A balance, heterogeneous body object.
Yet in actual mechanical process, often there is following several respects influence factor:
One, less than 5 ° small deflection angle
For the twisting vibration that guarantees balance is linear oscillator, its deflection angle needs less than 5 °, and majority is to rely on staff to stir balance in the current experiments equipment, is difficult to control the size of corner, if corner is excessive, is prone to nonlinear vibration; If corner is too small, the initial of cycle rocked in difficult judgement; Therefore, no matter corner is excessive or too small, all can impact measuring accuracy.
Two, balance radially wobbles
If by manually stirring balance; situation from its centre of gyration very easily appears unintentionally balance being dialled; make balance when work; not only there is twisting vibration; usually also can be accompanied by swing radially; this causes observer or measurement mechanism to be difficult to judge rocking the cycle, thereby measuring accuracy has also been caused influence.
Three, balance horizontally suspends
The use prerequisite of three string pendulum methods is the necessary horizontal positioned of balance, otherwise the phase countershaft OO of measured object
2Revolving shaft OO with balance
1Do not overlap, as shown in Figure 2, this will cause measuring error to increase.In the practical operation, normally adopt eye-observation or place the level that level meter is adjusted balance.Yet the former only with observer's subjective sensation, does not have reference data; Though the latter has level meter as the reference benchmark, adjust finish after, must withdraw level meter, therefore in measuring process, be difficult for observing whether level of balance.
Four, rock the measurement in cycle
Because " three string pendulums " method is according to equivalence principle, the cycle of rocking of determinand and the reference material of known moment of inertia are compared, thereby determine the moment of inertia of determinand, therefore, the measuring accuracy of moment of inertia and rock period measurement substantial connection is arranged.Because artificial counting error measuring period is bigger, for improving measuring accuracy, usually adopt the electronic type counting, existing sensing mode has infrared detection, magnetic field detection etc., but which kind of mode all need arrange an extra sign object at balance, as shown in Figure 3, this will cause actual rotation inertia and actual value to have difference.
