Description

The invention relates to computer technology and can be used to determine such basic parameters of a planar figure as area, static moment and its moment of inertia relative to any axis, as well as the coordinates of the center of gravity of this figure, its main central axes of inertia, moment resistance, volume, | θ static moment and center of gravity of bodies formed by the rotation of this figure about a given axis.

Known integrators containing a guiding element on which the carriage is mounted, on the carriage there is a disc clutch rotated 15, interfaced with integrating counters, a communication element made in the form of levers movably interconnected, and a by-pass sight connected to the communication element .

A disadvantage of the known integrators is that their integrating counters do not directly determine the values of the · sought quantities, to find which additional calculations are needed ’. .

The closest technical river to this is the L2 integrator} containing the first guide element 30 on which the carriage is mounted, the disk friction is rotated on the carriage, coupled to the first and second integrating counters, which are mounted respectively on the first and second sliders, which are respectively located on the second and third guiding elements, the second guiding element is fixed on the carriage, the fourth guiding element with the third slider installed on it, the communication element, execution nested in the form of a first rod and attached to it at right angles to the second rod, and a bypass sight IXJ.

The disadvantage of this integrator is the limited scope, because it does not allow to determine the moments of a plane figure without a value of its area, necessary to determine the coordinates of its center of gravity and the volume of bodies of revolution, and also continuously calculate the parameters of a plane figure lying simultaneously in both positive and in the negative regions of the coordinate axis values. In addition, the presence in this integrator of a multi-link communication element in the form of two cranked levers and a guide rod connected to them does not allow to obtain high accuracy of calculations.

The purpose of the invention is the increase in speed, accuracy and expansion of the scope of the existing integrator.

This goal is achieved by the fact that the third integrating counter, the fourth slider, the fifth and sixth guide elements, are introduced into the integrator in the second rod. A longitudinal slot is made in which the first slider is located, which is attached to the fifth guide element located perpendicular to the first guide element, parallel to which is the sixth guiding element, which is connected to the second slider and attached to the fourth slider connected to the first rod and located on the fifth on ravlyaetsya element bypass reticle and third integrating counter attached to the third slide which is pivotally mounted in the middle of the second rod, third and fourth guide members secured to the carriage.

The drawing shows a kinematic diagram of an integrator.

On the first guide element 1, a carriage 2 with a disk friction clutch 3 is installed. On the fourth guide element 4 there is a third slider 5 to which a bypass sight 6 and a third integrating counter are attached 7. On the second guide element 8, a first slider 9 is mounted to which the first integrating counter is attached a counter 10, and a second integrating counter 12 is mounted on the third guide element 11. The second 8, third 11 and fourth 4 guide elements are mounted on the carriage 2. The fourth slider 13 is connected to the first rod 14 element and the connection is located on the fifth guide element 15, which is attached to the first slider 9. The third slider 5 is mounted 'rotatable in the middle of the second rod 16 of the communication element, in the longitudinal slot of which the first slider 9 is located.

The sixth guide element 17 is attached to the fourth slider 13 and connected to the second slider 18, to which the second integrating counter 12 is attached.

The bypass sight 6 is paired with a tablet 19, on the surface of which a contour of the measured area is applied.

The integrator works as follows. .

. The first guide element 1 is placed along a predetermined axis, taken as the X axis, and the bypass sight 6 at the starting point of the contour of the measured area. The third slider 5 is moved so that the bypass sight 6 moves along the contour of the measured area in one direction. In this case, by means of the third slider 5, the four (the directing guide 4 movement is transmitted to the carriage 2 and the associated disk clutch 3, which drives the integrating counters 7, 10 and 12. In this case, the integrating counters are moved with respect to the axes of the disk clutch 3 at atgod distances , atg'oC, atg ^ t, where a is some instrument constant ', Οί is the angle of inclination of the first rod 14 of the coupling element to the X axis.
