摘　　要：目的设计一种能够高效强化太阳紫外光辐射强度的自然环境加速试验设备,在自然环境环境中,用于高分子材料及制品、零部件的耐光老化高加速试验与快速评估。方法自然环境超高加速光老化试验系统研制主要采用模块化设计思路,基于3个太阳辐射强化原理,开展紫外反射镜开发,设计系统总体结构、试验主机、太阳能供电分系统和控制分系统等,对主机结构进行有限元强度和变形量分析,开发以PLC为核心的控制系统和以触摸屏及计算机为媒介的人机交互软件。结果研制的自然环境超高加速光老化试验系统采用太阳能清洁能源供电,实现了40倍以上的太阳紫外辐射强化。结论研制的自然环境超高加速光老化试验系统加工与制造难度小,加速倍率高,环境友好,使用效费比高,更适用于户外装备用高分子材料及制品的耐光老化评估。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 enhance-ment 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 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.
