Abstract
A torsional pendulum rotational inertia tester with an angle scale mainly comprises a base, a central column, a spring frame, a power spring, a rotary shaft, a carrying disc, a light blocking rod and the angle scale. The torsional pendulum rotational inertia tester is characterized in that the central column (8) is connected with the base (9) and the spring frame (4), the outer end of the power spring (7) is fixed to the middle of the spring frame (4), the inner end of the power spring (7) is fixed to the rotary shaft (6), the rotary shaft (6) penetrates through the spring frame (4) and then is connected with the carrying disc (5), the light blocking rod (1) is connected to the carrying disc (5), the angle scale (3) is fixed to the upper end face of the spring frame (4) through angle scale screws (2), a horizontal bubble is located below an observation window (10) of the angle scale, and dividing scales from 0 degree to 360 degrees are carved on the upper end face of the angle scale (3).
Description
Technical field
The present invention relates to Experiment of College Physics torsional pendulum moment of inertia testing apparatus, relate generally to a kind of torsional pendulum moment of inertia testing apparatus with angle scale.
Background technology
useit is the physical experiment apparatus course that a kind of a lot of colleges and universities offer that torsional pendulum type moment of inertia testing apparatus measures moment of inertia.In order to energy Measurement accuracy moment of inertia, it is one of fundamental that the initial angle rocked controls at 90 degree.Rely on now operator to estimate to grasp the initial angle rocked completely, variant between different operators, also variant between each operation of same operator, this will bring error to measurement result.
Summary of the invention
The initial angle that rocks during in order to accurately control rotation inerttia is 90 degree, and the present invention devises a kind of torsional pendulum moment of inertia testing apparatus with angle scale.
Band angle scale of the present invention torsional pendulum moment of inertia testing apparatus mainly comprises base, newel, spring(-supported) mount, clockwork spring, rotation axis, carrying disk, be in the light bar and angle scale.Angle scale is fixed on the upper surface of spring(-supported) mount, and the calibration groove of 0--360 degree is carved with in the upper surface of angle scale, also has a view window, under the horizontal bubble of torsional pendulum moment of inertia measuring instrument is positioned at the view window of angle scale.During use, first write down the angle index below the static bar that is in the light, rotate above the bar to the scale adding 90 that is in the light, also can turn to above the scale subtracting 90 degree, then to loose one's grip beginning surveying work, each measurement, only need forward the bar that is in the light above the scale just now determined to and unclamp, and just can ensure that each angle of initially rocking is identical and equal 90 degree.
The invention has the beneficial effects as follows that the initial angle that can ensure to rock is 90 degree, and each measure initially to rock angle identical, be conducive to the measuring accuracy improving moment of inertia.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the overall schematic of the torsional pendulum moment of inertia testing apparatus of band angle scale.
Fig. 2 is angle scale schematic diagram.
In figure, 1, be in the light bar, and 2, angle scale screw, 3, angle scale, 4, spring(-supported) mount, 5, carrying disk, 6, rotation axis, 7, clockwork spring, 8, newel, 9, base, 10, view window.
Embodiment
In fig. 1 and 2, newel (8) connects base (9) and spring(-supported) mount (4), the outer end of clockwork spring (7) is fixed on the middle part of spring(-supported) mount (4), the inner is fixed on rotation axis (6), rotation axis (6) is connected with carrying disk (5) afterwards through spring(-supported) mount (4), the bar (1) that is in the light is connected on carrying disk (5), and angle scale (3) is fixed on the upper surface of spring(-supported) mount (4) by angle scale screw (2), and horizontal bubble is positioned at the below of the view window (10) of angle scale.Can there be the calibrated dial of 0--360 degree the upper surface of angle scale (10).
