根据整车噪声实验室的使用和性能要求,介绍了其消声室及试验台设计。消声室为半消声室,主体关键设计为吸声结构、隔声门和隔振系统,其他系统作为辅助;试验台采用一轴双鼓、单驱,转鼓是试验台的核心,转鼓的表面是决定测试准确性的最主要因素之一。 According to the use of vehicle noise laboratory and performance requirements, introduced its anechoic chamber and test bed design. The anechoic chamber is a semi-anechoic chamber. The key design of the anechoic chamber is acoustical absorption structure, sound insulation door and vibration isolation system, and other systems are used as auxiliary. The test bench adopts single shaft double drum and single drive. The drum is the core of the test bench. The surface of the drum is one of the most important determinants of test accuracy.
