噪声是混凝土搅拌机的质量评价指标之一。为了控制混凝土搅拌机的噪声,必须对噪声源进行分析、研究,并采取有效的降低噪声的措施。本文通过对JZ350型混凝土搅拌机的测试结果进行分析,试图说明JZ系列搅拌机的搅拌机理、传动方式等对噪声的影响,探讨降低噪声的途径。一、测量数据降低噪声或噪声控制,倍频程数据是必要的。在分析噪声时,常需要1/3倍频程或窄带
Noise is one of the quality evaluation indicators of concrete mixers. In order to control the noise of the concrete mixer, the noise source must be analyzed and studied, and effective noise reduction measures must be taken. This article analyzes the test results of the JZ350 concrete mixer and tries to explain the influence of the stirring mechanism and transmission mode of the JZ series mixer on the noise, and discusses ways to reduce the noise. First, measurement data to reduce noise or noise control, octave data is necessary. When analyzing noise, it often requires 1/3 octave or narrow band
