Development of Multifactor Integrated Frigid Plateau Climate Simulation and Acceleration Test Chamber

The paper aims to develop a multifactor integrated frigid plateau climate simulation and acceleration test chamber for fast screaming and environmental worthiness evaluation of technology, material and parts to be used in frigid plateau. Through plateau climatic characteristic analysis, technology verification, and literature analysis, design, manufacture, test spectrum design and test were carried out. The problem of simultaneous application of radiation with high-low temperature and high-low air pressure was solved and a multifactor integrated frigid plateau climate simulation and acceleration test chamber was developed. A set of test spectrum was designed and multifactor integrated simulation and acceleration test of frigid plateau climate were realized. Technical indicators of the test chamber meet design requirements. In terms of the tensile strength and impact toughness of plastics, color difference and gloss change of organic coating, the test result has good correlation and high acceleration compared with outdoor exposure test results of Lhasa station. The test chamber can be used in fast screaming and environmental worthiness evaluation of technology, material and parts to be used in frigid plateau.
