(54) TOOLS FOR ENHANCING THE CENTER OF EFFICIENCY The invention relates to a testing technique and can be used to determine the center of gravity of agricultural machines. A device for determining the center of gravity of products is known, comprising a base, curvilinear guides mounted on it and moving along the guides to a static equilibrium position and a carriage for mounting the product Q on it. A disadvantage of the device is that the determination of the center of gravity of the articles is related significant inconvenience in the work, as the cart moves and the product must be rearranged. The closest in technical essence to the invention is a device for determining the center of gravity of products containing a base, platforms installed on a base that can be rotated around a horizontal axis, and force-measuring elements: mounted on a platform | j2. The disadvantage of this device is that. during measurements, non-vertical forces appear, since the subject under test is tilted together with the platform. These forces reduce the accuracy of measurements. The purpose of the invention is to increase the measurement accuracy. The fixed objective is achieved by the fact that the device is equipped with lifting plates and brackets, installed, respectively, on force measuring elements and plug-in, and rigidly closed on brackets with connecting rods, placed along the perimetrum at the plates and fixed on them. FIG. 1 tfedstavleno offer e device, front view; in fig. 2 - Oh, top view; in fig. 3 - load plate, general view. The device contains a base 1, a platform 2 installed on the basis of cues with the ability to rotate around the pot axial axes OO and 0, the force-bearing elements 3 and 4 are set TH-- Elatfsrmy,; reziodem in shtshty 5 - 8, mounted on the load cells, the bracket 9 - 12, mounted on platform 2, and connecting rods rigidly mounted on the brackets 13 16, placed around the perimeter of the plates and fixed on them (in the drawings All load elements, rods and brackets are not listed). The device also contains an assembly-mounted engine 17, mounted on a base, connected kinematically to platform 2 and allowing it to be lifted, and a measuring console 18. The test also shows the product being tested - the agricultural machine 19. The device works as follows. Test machine 19 with locked running wheels mounted on a horizontally positioned platform so that the travel wheels were mounted on the horizontal plate slabs. The wheel pressure is then measured by means of load cells. Next, the engine 17 tilts the platform 2 alternately around horizontal mutually perpendicular axes. In each of the inclined positions of the platform, pulp 18 readings of the measuring elements are measured. The measuring console, summing up the corresponding readings of the force-measuring elements, determine the position of the gravity plate and the limiting angles of stability of the machine. 19, When inclined, the lifting plates do not move in the lateral and longitudinal directions, as the connecting rods prevent this. The device makes it possible to increase the accuracy of measurements of the center of gravity and the limiting stability angles, which is important for agricultural machines, whose complexity and construction and dimensions should best fit the configuration of the terrain in which they operate.
