Full Vehicle Sunlight Simulation Test Chamber
Applications
Full Vehicle Sunlight Simulation Test Chamber is designed to evaluate the aging performance of complete assemblies or entire vehicles under sunlight exposure. Users can assess changes in performance after irradiation, including alterations in shape, color, gloss, texture, strength, and various thermal expansion results. Additionally, it tests key metrics such as vehicle starting capability, motor performance, and overall air conditioning functionality under solar radiation.
