Abstract：Display consoles are mostly used for long-term information reading and command control,which easily causes fa-tigue.The ergonomics level of display console has been paid more attention.In order to compare different standards for the display console screen angle,and find the most ergonomic angle,this research studied changes in the back muscle fatigue of operators at different angles of display console screens.Firstly it compares two commonly-used angles of a display console screen,which are-15°and+15°,and uses 0°for a comparison experiment.Then it collects the value of electromyographic signals of the fatigue of back muscles,the integral electromyography,root median square and mean power frequency are chosen for analysis.It is finally found that fatigue accumulation is most obvious with a display console screen angle of-15°.There is little difference in fatigue be-tween the remaining two angles.Part of the data also shows a trend of voluntary relief of fatigue.The results of this study provide a reference for the information layout design of display consoles and the ergonomic standard setting of display console screens.
