摘要
对某型吸油烟机进行振动和噪声测试与分析,目的是找出该机型的主要振动和噪声源。根据国家标准,在半消声室条件下,采用传声器和振动加速度计等精密仪器对其振动和噪声进行测量,并采用频谱分析等手段分析了测量数据,找出了主要的噪声源,并对产品设计提出了改进意见。
Vibration and noise measurement and analysis are completed to a range hood. The aim is to find out the main vibration and noise source. According to the national standard of China about household electrical appliance, pressure and acceleration are measured in a semi-anechoic chamber with microphones and accelerators. Power spectrum analysis is also performed to the measured data. The main sound source is found out at last, and advices are given to improve the product designing.
