摘要
脉冲激励阻尼振动在实际生活中经常发生,并且对人体健康具有一定的危害,如何对其评价是工程中需要解决的问题。本文试图将ISO 2631/CD—1991委员会草案提出的振动对人体健康影响的评价方法,应用于脉冲激励阻尼振动的评价,并进一步将脉冲激励阻尼振动简化为一定暴露时间的脉冲正弦振动,以简化评价过程。最后,着重讨论了作用于坐在座椅上人体纵向的脉冲激励阻尼振动对健康影响的评价。
It is a problem how to evaluate the influence of damped vibration due to pulses, which are encountered frequently in everyday life, to human health. To solve the problem, the method in the ISO 2631/CD-1991 committee draft may be used, and further simplified to evaluate the effect of damped sinusoidal vibration due to pulses in equivalent exposure time. Moreover the evaluation about the longitudinal damped vibration due to pulses applied to the human body sei-tled on the chair, is analyzed briefly.
