| 目的 研究自然界降雨量与汽车环境风洞模拟降雨量之间的关系，得到中国气象条件的雨量设定经验公式，为汽车环境风洞模拟降雨量的设定提供理论依据。方法 理论分析自然界气象降雨和汽车环境风洞模拟降雨的特点和差异，研究影响汽车环境风洞模拟降雨量的因素。结果 在无风条件下，影响汽车环境风洞降雨量的因素有气象降雨量、前挡风玻璃倾角、雨滴直径和车速等。按照车速将降雨分为汽车停止和汽车行驶2种模式，提出结合中国气象条件的汽车环境风洞模拟降雨量的经验公式。结论 在相同降雨等级下，汽车停止状态下的汽车环境风洞降雨量一般大于车辆行驶状态。在气象降雨量等级为短时中雨时，行驶汽车的雨量设定值与车速呈指数增长关系。 |

| The work aims to study the relationship between natural rainfall and vehicle climate wind tunnel simulated rainfall, and obtain the empirical formula of rainfall setting in Chinese climate, so as to provide a theoretical basis for the setting of vehicle climate wind tunnel simulated rainfall. The characteristics and differences between natural meteorological rainfall and vehicle climate wind tunnel simulated rainfall were analyzed theoretically, and the factors affecting the vehicle climate wind tunnel simulated rainfall were studied. Under the condition of no wind, the factors affecting the rainfall of vehicle climate wind tunnel included meteorological rainfall, tilt angle of front windshield, raindrop diameter and vehicle speed. According to the vehicle speed, the rainfall was divided into two modes:vehicle stop and driving. An empirical formula for simulating rainfall in vehicle climate wind tunnel combined with Chinese climate was proposed. At the same rainfall grade, the rainfall of vehicle climate wind tunnel during vehicle stop is greater than that during driving. When the meteorological rainfall grade is short-term moderate rain, the rainfall setting value of the driving vehicle increases exponentially with the vehicle speed. |
