Description
technical field [0001] The invention relates to the technical field of material weather resistance test equipment, in particular to a weather resistance test device for train insulating materials under high-speed airflow. Background technique [0002] The construction of the Sichuan-Tibet Railway is of great and far-reaching significance to the long-term stability of our country and the economic and social development of Tibet. However, the construction of the Sichuan-Tibet line requires a more in-depth study of the impact of high-altitude environments on materials, and the Sichuan-Tibet line is designed as an electrified high-speed railway. Simulating the high-speed airflow environment is an important prerequisite for studying the performance of train insulation materials, so that more in-depth research can be carried out at high altitudes. UV resistance of materials under high-speed airflow at altitude. For the ultraviolet aging test of materials in high-altitude environm...
