防飞溅装置测试能力研究

Study of the test capability on spray-suppression devices

大型汽车雨天高速运行时从轮胎两侧飞溅出来的泥浆和水雾,影响两侧车道其他车辆上驾驶员的视线及安全。防飞溅装置可有效地减少车辆运动时轮胎向上溅起的泥浆和水雾,有效地防止交通事故发生。GB34659-2017《汽车和挂车防飞溅系统性能要求和测量方法》中,规定了防飞溅装置的技术要求和测量方法。本文详细介绍了防飞溅装置的定义及一般结构型式、技术要求、测量方法、测试设备的研制。

The mud and water mist produced by the large vehicles on the both sides during high speed driving affects the other driver's sight and safety.Spray-suppression devices will effectively reduce the mud and water mist while driving,and prevent traffic accidents.GB34659-2017"Requirements and test methods relating to the spray-suppression systems of motor vehicles and their trailers"introduce the technical requirements and test methods of the spray-suppression devices.In this article,the definition,the general structural styles,the technical requirements,the test methods and the research and development of test devices of spray-suppression devices are summarized in detail.
