| 中文摘要: |
| 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。 |
| 英文摘要: |
| The design of anechoic chamber and test bench of whole vehicle noise test laboratory was introduced according to the application requirements.The anechoic chamber was semi-anechoic chamber including sound absorption structure，sound proof door, vibration isolation system and auxiliary system.The test was performed with 2 rollers driven by one machine and one axle on the test bench.The rollers were the key component of test bench and the surface of rollers was the key factor to the accuracy of noise test results. |
