| Solar ultraviolet radiation is one of the main factors that cause the aging and performance degradation of outdoor polymer materials and products. The work aims to design an accelerated test equipment under natural environment that can effectively enhance the intensity of solar ultraviolet radiation and can be used for the high accelerated test and rapid evaluation of the light aging resistance of polymer materials, products and parts. The development of the ultra-accelerated UV aging test system under natural environment mainly adopted the modular design idea. Based on three principles of solar radiation enhancement the development of the ultraviolet reflector was carried out and the overall structure of the system, the test host, the solar power supply subsystem and the control subsystem were designed. The finite element strength and deformation of the host structure were analyzed, and the control system with PLC as the core and the human-computer interaction software with touch screen and computer as the media was developed. The ultra-accelerated UV aging test system under natural environment was powered by solar energy, which realized more than 40 times of solar ultraviolet radiation enhancement. The test system developed in this work has the advantages of high acceleration rate, environmental friendliness and high efficiency cost ratio, and is more suitable for the evaluation of UV aging resistance of polymer materials and products for outdoor equipment. |
