Human reactions to whole-body transverse angular vibrations compared to linear vertical vibrations.

摘要: An electro hydraulic vibration device was used to study the effects of some forms angular motion in transverse mode and a combination vertical motion, common ground vehicles. Heart rate, tracking error, hip shoulder acceleration, subjective judgements three subjects were recorded under different test conditions using seats. The excitation acceleration had 0-25 0-50 g peak linear component on seat at frequencies 1, 1-7, 2-5, 40 Hz. Man is more affected shows degraded performance influence than vibrations alone. Worst motion. Tractor seats good for are not necessarily
