FIELD: functional testing of devices for measuring linear or angular speeds, accelerations, decelerations. ^ SUBSTANCE: single-axis stand for testing devices under effect from centrifugal forces in various climatic modes contains a drive with platform mounted on its output shaft, on which platform, coaxial to output shaft of drive, a device for transferring and returning heat flows is mounted, made of rotating and non-rotating parts. The device for transferring and returning heat flows is provided with air ducts, first one of which by one end is connected to hollow of non-rotating part output of device, and second one by one end is connected to hollow of rotating part of device. Other ends of air ducts are connected to testing chamber, which has, mounted inside, a splitter, connected to first air duct, and a heat flow separator. The hollow limited by heat flow separator is connected to second air duct. Testing chamber with the device being tested is positioned at given distance from the axis of output shaft of the drive and connected to hollows of the device for transferring and returning heat flows, which are connected to hollows of ventilators by means of flexible tubing, held by one ends on non-rotating part of device for transferring and returning heat flows, and by other ends connected to hollows of ventilators, connected in its turn to hollow of the climatic chamber. ^ EFFECT: testing of devices under effect from centrifugal forces in various climatic modes with minimal financial and energy resource costs. ^ 9 dwg |
