摘　　要：为了研究中国驾驶人响应及疲劳限值,选择8名志愿受试者,通过心理学评价方法得到了中国人脚部受振疲劳限值,依次使20名志愿受试者承受该标准激励,得到了6.3-80Hz范围内等感觉振动加速度,通过数据处理得到了中国人脚部受振频率计权曲线。研究结果表明：6.3-16Hz频率范围内试验得到的中国人脚部振动频率加权曲线与ISO 2631—1997规定的曲线基本一致,但是在16-80Hz频率范围内,试验结果曲线明显大于ISO 2631—1997规定的曲线,证明在该频率范围内中国人脚部对振动更为敏感,因此中国投产的车辆应该在产品设计和人机工程学方面加以重视。In order to study the response and fatigue limit values of Chinese drivers, 8 trial volunteers were chosen for a test. The fatigue limit value of feet vibration of Chinese drivers was acquired via psychological evaluation. The equal feelings of vibration acceleration within the range of 6.3-80 Hz were obtained through the test in which 20 trial volunteers were arranged in turn to take the standard stimulation. The frequency weighting curve for feet vibration of Chinese drivers was obtained by processing the above data. The results show that within the frequency range of 6.3-16 Hz, the frequency weighting curve for feet vibration of Chinese drivers is in the similar trend with the curve prescribed in ISO 2631-1997% nevertheless, within the frequency range of 16-80 Hz, the values on frequency weighting curve for feet vibration of Chinese drivers are significantly greater than those on the curve prescribed in ISO 2631-1997. This indicates that Chinese drivers are more sensitive to vibration on their feet within the vibration frequency range of 16-80 Hz. Therefore, product design and ergonomics shall be valued for the design and manufacture of domestic motor vehicles. 8 tabs, 2 figs, 16 refs.
