||Whole-body vibration exposure study in U.S. railroad locomotives - An ergonomic risk assessment
||July-Aug. 2002, Vol.63, No.4, p.439-446. Illus. 28 ref.
||Whole-body vibration exposure of locomotive engineers and the vibration attenuation of seats in 22 locomotives built between 1959 and 2000 was studied using international measurement guidelines. Triaxial vibration measurements on the seat and on the floor were compared. In addition to the basic vibration evaluation, the vector sum, the maximum transient vibration value, the vibration dose value and the vibration seat effective transmissibility factor were calculated. The power spectral densities were also reported. It was found that locomotive rides are characterized by relatively high shock content (acceleration peaks) of the vibration signal in all directions. Locomotive vertical and lateral vibrations are similar, which appears to be characteristic for rail vehicles compared with many road and off-road vehicles. Tested locomotive cab seats currently in use (new or old) appear inadequate to reduce potentially harmful vibration and shocks transmitted to the seated operator, and older seats particularly lack basic ergonomic features regarding adjustability and postural support.
