| 摘 要： | 通过对某沥青混凝土摊铺机各主要声源的近场声和驾驶员耳旁噪声进行测试分析,识别出对驾驶员耳旁噪声贡献较大的噪声源.针对这些噪声源的特性采取相应的降噪措施,在进、排风口分别设计了消声结构,使摊铺机噪声明显降低.测试结果表明,该摊铺机噪声指标达到了国家标准规定的水平.

| Abstract: | By means of measurement and analysis of noise near certain asphalt-spreader's driver's ear and near-field noise of main noise sources, the noise source whose contributions to noise near driver's ear was rather strong was identified. According to the characteristics of the noise source, noise reduction structure was designed in outlet and inlet of cooling system respectively, it turned out spreader noise is decreased obviously. Result of measurement indicates noise of the spreader measure up to the national standard. |
