Driving mechanism life test environment simulation equipment
The driving mechanism life test environment simulation equipment mainly provides a simulated on orbit space environment (temperature gradient, vacuum degree), so that the mechanism can work according to the actual working conditions in this environment. It is mainly used for the thermal vacuum test and accelerated life test of the two-dimensional pointing mechanism to the sun orientation device, so as to fully verify the reliability of the driving mechanism. The equipment adopts composite working fluid and heat transfer oil dual refrigeration technology, which can realize independent temperature regulation of heat sink and cold plate, and is conducive to improving the temperature rise and fall rate and temperature control accuracy of large heat capacity test products.
