Descriptive analysis of combine cabin vibrations and their effect on the human body

摘要: Abstract All on- and off-road vehicles are exposed to vibrations caused by unevenness of road or soil profile, moving elements within the machine implements. A higher prevalence low back pain is found in drivers machinery than other drivers. In this study, significantly levels low-frequency cabin a combine, driving at high speed (20 km/h ) on concrete surface, compared slower field road. Comfort values indicate that injury can result from long-term as well As seats with suspension systems main transmission paths vibration towards spine driver, their attenuating characteristics play an important role comfort assessment. The resonant frequency passive system, used agricultural machinery, lies range most excited machinery. seat air attenuate better frequencies above 4 Hz provide more driver mechanical suspension.
