<p><P>PROBLEM TO BE SOLVED: To provide an allowed time computing device for work under application of vibration for protecting health of a worker working under strong vibration/noise for a long time in a vehicle and the like. <P>SOLUTION: This allowed time calculation device for work under vibration is constructed of a vibration acceleration sensor means 2 arranged in a seating part of a seat in the vehicle and the like, a first computing means 3 inputting a detection signal from the vibration acceleration sensor means 2, a second computing means 4 inputting a synthetic correction value a<SB>i</SB>, which is computed by the first computing means 3, of vibration acceleration received from the seating part and computing an allowed residual time T<SB>r</SB>allowed for continuous work under vibration from a predetermined time T<SB>0</SB>serving as a reference and an acceleration a<SB>0</SB>, and a display means 5 displaying the allowed residual time T<SB>r</SB>computed by the second computing means 4. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
