Abstract: The influence of impact and vibration on the personnel heart rate variability (HRV) was studied using biomedical
monitoring equipment to protect the driver and passenger security. Impact tests show that the heart rate increases by 1.4% to
44.3% with decreasing rMSSD (root mean square successive difference), LF (low frequeuce), and HF (high frequence), but
increasing LF/HF. Vibration tests show that the average heart rates of the driver and co-driver increase by 12.6% and 4.8% after
one hour's driving, with the rMSSD, LF, and HF being decreased, but the LF/HF being increased. The results indicate that the
activities of the sympathetic nerve and pneumogastric nerve are weakened, and the psychological tensity trend is enhanced with
increasing age and responsibility. Therefore, the HRV can be used to analyze the tension, fatigue as well as security monitoring,
with broad prospects for application and research.
