运动环境响应对人的简单反应时的影响研究

The Research on the Effects of Vibration Environment on Human Simple Reaction Time

人们在工作生活中常常处于振动环境条件下,不同的振动对人的生理、心理等会有不同程度的影响。对视觉目标水平振动对人的简单反应时的影响进行研究。文中采用人体反应时测试软件,通过构建视觉目标与人眼的相对振动环境,测试不同振动条件下人的视觉反应时,分析了简单反应时同振幅和频率等参数的关系,拟合出频率—反应时间、振幅—反应时间的函数关系。结果表明:振幅的增加会导致反应时间的增加;从振动频率看,在低频率范围反应时间随频率增加而增加,在高频范围内反应时间随频率的增加变化不大。的工作为振动环境下人机界面和工作空间的设计提供了依据。

People often work and live under the vibration environment. Different vibration excitations have different effects on people＇s physiology arid psychology.studies the effects of visual object＇s horizontal vibration on simple reaction time by using testing software. The reaction time is measured by simulation of relative movement between visual target and human eyes. The relationships between simple reaction time, amplitude, frequency and other vibration parameters are analyzed and fitting function of frequency-reaction time and amplitude-reaction time are obtained. The results indicate that the reaction time increases with the increase of amplitude; in consideration of the vibration frequency, the reaction time increases with the increase of frequency in the low frequency range, the reaction time changes little with the increase of frequency in the high frequency range. The work provides the foundation for the design of man-machine interface and working space under the vibration environment.
