This fills a gap in the existing ISO whole-body vibration standard, which does not adequately predict TGV occupants' lower back injuries that may be due to repeated shocks. Both Part 1 and the new Part 5 of ISO 2631 standard were implemented in an interactive graphical user interface (GUI) tool and transitioned to users who conduct HHAs of Army systems. As reported here, the GUI tool was used to compare the two standards. The comparison shows that the old standard often fails to detect adverse health effects of repeated shocks, which are clearly identified and accounted for by the new standard method. 收起
