首套冰雪气候模拟系统研制成功

Core Viewpoint - The successful development of the "Wind-Rain-Heat-Snow Joint Simulation Test System" by Harbin Institute of Technology marks a significant advancement in China's ice and snow engineering research, entering a new era of comprehensive factor coupling [1] Group 1: System Features - The test system integrates five major functional modules, including a low-temperature wind tunnel that can replicate a -20°C wind field [1] - An intelligent snowfall module controls the morphology of snow crystals, while a dual-mode rainfall system finely adjusts raindrop spectra [1] - A solar radiation array simulates sunlight at different latitudes, and a monitoring center tracks the phase change of snow in real-time [1] Group 2: Research Implications - The system creatively addresses the simulation research of snow accumulation changes on roofs under multi-factor conditions of wind, rain, heat, and snow [1] - It maximally restores the periodic changes of snow accumulation, drifting, melting, crystallization, and re-accumulation on large roofs, providing real data for snow load research [1] Group 3: Applications and Support - Since passing acceptance, the system has provided technical support for accurately determining snow loads on roofs for several national major construction projects [1] - It also supports the national polar strategy by offering essential technical backing [1]
