一、人与振动振动环境对人体的影响,包括人体对振动的功能生理反应和振动条件下的工作效能与安全限度等,近年来已引起航天航海、交通运输、劳动保护、仪器制造等各方面专家的广泛关注。由于在许多情况下,如运输器具、工程机械、动力机组的操作者与乘员所处的振动环境,对人体常呈现有害的影响,因此研究人体对振动的感受必须考虑其动力学特征和振动环境诸因素:如振动的频谱、强度、方向、传输点和暴露时间等。
First, the human and vibration Vibration on the human body, including the body’s physiological response to vibration and vibration under the conditions of work efficiency and safety limits, in recent years has caused spaceflight, transportation, labor protection, equipment manufacturing and other aspects Wide attention of experts. Since in many cases the vibration environment in which operators, passengers and crew of transport equipment, construction machinery, power units are located, often has a detrimental effect on the human body, studying the human body’s perception of vibration must take into account its dynamics and vibrational environment Various factors: such as vibration spectrum, intensity, direction, transmission point and exposure time.
