一、前言众所周知,手传振动可致振动病(又名职业性雷诺氏症或振动综合症)。但振动剂量大小与人体反应强弱之间关系尚不十分清楚,此外,不同频率和振级作用于人体的反应也不甚清楚;而作业环境中的某些因素如噪声、气溫、加工件硬度和手持工具的握力等对剂量-反应关系所起的作用也不够肯定。近年来由于电子工业的迅速发展给振动测试提供有利条件,另方面由于流行病学广泛应用于振动 First, the preamble As we all know, hand vibration can cause vibration disease (also known as occupational Raynaud’s disease or vibration syndrome). However, the relationship between the magnitude of the vibrational dose and the strength of the human body is not yet clear. In addition, the responses of different frequencies and vibration levels to the human body are also not clear. Some factors in the working environment, such as noise, temperature, Hardness and hand-held tools such as grip strength on the role of dose-response relationship is not sure. In recent years due to the rapid development of the electronics industry to vibration test provides favorable conditions, on the other hand due to epidemiology widely used in vibration
