Abstract
The invention discloses an angle controller of a torsional-pendulum rotation inertia measuring instrument. The angle controller mainly includes a gag lever post and a connection rod which sleeves a center pole of the torsional-pendulum rotation inertia measuring instrument and is capable of sliding up and down and also capable of rotating randomly around the center pole, wherein the connection rod is fixed on the center pole through a screw. The gag lever post is fixed on the connection rod. A top end of the gag lever post is higher than a light blocking rod which is arranged horizontally for 0-10 millimeters. A gag lever post screw (6) adjusts the height of the gag lever post (2). During use, the fixing position of the connection rod on the center pole of the instrument is adjusted so as to enable the light blocking rod to rightly contact the gag lever post when starting to rotate for 90 degrees from a static position and then in follow-up measurement at each time, only the light blocking rod needs to be rotated to the position of the gag lever post so as to contact the gag lever post and then released and thus it can be ensured that an initial torsional-pendulum angle at each time is identical and equal to 90 degrees.
Description
Technical field
The present invention relates to Experiment of College Physics torsional pendulum moment of inertia measuring instrument, relate generally to the restricted problem of the initial angle rocking.
Background technology
Torsional pendulum type rotation inerttia instrument is the physical experiment apparatus that a kind of a lot of colleges and universities offer.For energy Measurement accuracy moment of inertia, it is one of fundamentals that the initial angle rocking is controlled at 90 degree.Now rely on operator to estimate to grasp the initial angle rocking 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 when accurately controlling rotation inerttia is that 90 degree and each angle are identical, and the present invention has designed a kind of torsional pendulum moment of inertia measuring instrument angle controller.
Torsional pendulum moment of inertia measuring instrument angle controller of the present invention mainly comprises gag lever post, connecting link, connecting link is sleeved on the newel of torsional pendulum moment of inertia measuring instrument, can slide up and down, also can rotate arbitrarily around newel, by screw, be fixed on newel, gag lever post is fixed on connecting link, and the top of gag lever post is higher 0-10 millimeters than the bar that is in the light of horizontal positioned, and gag lever post screw (6) regulates the high and low position of gag lever post (2).During use, regulate connecting link fixed position on centre post, the bar that makes to be in the light starts to rotate 90 from rest position and just contacts gag lever post while spending, ensuing each measurement, only the bar that is in the light need be forwarded to after gag lever post place contacts with gag lever post and unclamps, identical and equal 90 degree with regard to guaranteeing each angle of initially rocking.
The invention has the beneficial effects as follows and can guarantee that the initial angle rocking is 90 degree, and each measure initially to rock angle identical, be conducive to improve the measuring accuracy of moment of inertia.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the scheme of installation of torsional pendulum moment of inertia measuring instrument angle controller.
Fig. 2 is that the bar that is in the light turns over 90 while spending and the firm accessible schematic diagram of gag lever post from rest position.
In figure, 1, the bar that is in the light, 2, gag lever post, 3, connecting link, 4, screw, 5, newel, 6, gag lever post screw.
Embodiment
In Fig. 1 and Fig. 2, connecting link (3) is sleeved on the newel (5) of torsional pendulum moment of inertia measuring instrument, can slide up and down, also can rotate arbitrarily around newel, fixing by screw (4), gag lever post (2) is fixed on connecting link (3), the top of gag lever post (2) is than the high 0--10 millimeter of the bar that is in the light (1) of horizontal positioned, gag lever post screw (6) regulates the high and low position of gag lever post (2), gag lever post (2) and the fixed position of connecting link (3) on centre post (5) are that the bar (1) that makes to be in the light starts to rotate 90 from rest position and just contacts gag lever post (2) while spending.
Claims (2)
1. a torsional pendulum moment of inertia measuring instrument angle limiter, mainly comprise gag lever post, connecting link, it is characterized in that connecting link (3) is sleeved on the newel (5) of torsional pendulum moment of inertia measuring instrument, fixing by screw (4), gag lever post (2) is fixed on connecting link (3), the top of gag lever post (2) is than the high 0--10 millimeter of the bar that is in the light (1) of horizontal positioned, gag lever post screw (6) regulates the high and low position of gag lever post (2), gag lever post (2) and the fixed position of connecting link (3) on centre post (5) are that the bar (1) that makes to be in the light starts to rotate 90 from rest position and just contacts gag lever post (2) while spending.
