SU1675714A1 - Stand for comprehensive tests of objects - Google Patents

Abstract

The invention relates to testing equipment, in particular, to stands for the complex effect of external factors. The goal is to increase the number of external influencing factors by providing the effect of the active substance and expanding the range of dynamic loads, as well as reducing the size of the centrifuge. The bench allows the test object to be subjected to complex effects of linear accelerations, dynamic loads, elevated temperatures, excessive or negative pressure, as well as the active substance. The stand contains support pipe 1, heat chamber 2, power pipes 3 and 4, counterweight 5, ring guide 6 with holders 7 cantilever rods 8 and their drives 9. Heat chamber 2 contains a heater, a rotary table with a test object and a drainage relief valve . The cantilever rods 8 interact with the two shoulders lever 15 pivotally mounted at the ends of the power pipelines 3 and 4 with the ability to interact with the turntable. Heat chamber 2 is connected through power pipelines 3 and 4, thermocollectors, shut-off elements and support pipe 1 with a source of active substance supplied under conditions of excessive or negative pressure. 1 hp f-ly, 3 ill. with VO fc

Claims (2)

Claim 1. A test bench for complex testing of objects, containing a centrifuge mounted on the base with a frame and a drive for its rotation, a heat chamber with a heater and a rotary table for the test object mounted on opposite ends of the frame and a counterweight, a dynamic loading device connected to the rotary table, characterized in that , in order to increase the number of external factors due to the impact of the active substance and expand the range of implemented dynamic loads, the stand is equipped with lump of active substance with a ventilation system associated with the heat chamber, and the dynamic loading device is made in the form of an annular guide located on the base around the centrifuge with pivotally mounted on it with the ability to linearly move and change the angle of inclination of the cantilever rods and the two-arm lever pivotally mounted on the frame , one shoulder of which is made in the form of a console with an angular cut located with the possibility of interaction with a rotary table and with cantilever arms by levers, and the other shoulder is connected through an elastic element with a frame. 2. The stand according to claim 1, with the fact that, in order to reduce the size of the centrifuge, one half of the frame is made in the form of power pipelines connected through pressure collectors and shut-off elements with a heat chamber and a source active substance with a ventilation system, and the other half of the frame is made with guides. at the same time, the rotary table and the two-arm lever located in the heat chamber are pivotally mounted at the ends of the power pipelines associated with the heat chamber, and the drive is made in the form of a counterweight mounted on the guide? with the possibility of radial movement, Fig.3 Editor S.
