ESTIMATING THE EFFECT OF BLAST SHOCK VIBRATION ON HEALTH OF HUMAN-BODY

讨论了爆炸冲击振动对人体健康影响的评价方法，阐述了振动剂量法提出的依据和影响因素，并用振动剂量法统一了爆炸冲击和振动下人体耐受限的取值方法，提出了取VDV＝25m·S-1.75作为爆炸冲击振动下保证人员安全的容许振动剂量值。

This paper discusses the methods of estimating the effect of blast shock vibration on health of human-body . At present, in the design of shock isolaion system some prescribed acceleration values have been generally used as the human shock tolerance or vibration tolerance. However, experimental results indicate that the human tolerance is directly related with the peak value of acceleration , the duration of shock or vibraion and the dynamic characteristics of hnman body. The correlativity of human tolerance with the shock or vibration duration i reveals tha the human tolerane of health has a time-accumulation tffect.So the shock tolerance and vibration tolerance of human body under the blast environment can be unified on the basis of the priciple of accumulated damage. In this paper, the VDV method has bo introduced into the blast environment to unify the human tolerances of shock and vibration, to study the effect of blast shock and vibration on the health, and to analyze the safe values of shock vibration accelertiaons to human health- According to the analysis in the paper, the VDV = 25m.s-1.75 is an appropriate value for evaluating human health in the blast shock and vibration environment.
