Amenity modeling and optimal design of helicopter cockpit steering apparatus

Contrapose the problem of helicopter cockpit steering apparatus comfort, a 5 degrees freedom man upper arm movement model is established. Considering the influence of biostatics for pilot subjective comfort, the RULA method is introduced to the establishment of upper arm introduce model. Adopting China helicopter pilot anthropometric data, contrasting the result of CATIA system emulator, the rationality and practicability of the model is validated. Using collective pitch control layout design as example, the corresponding apparatus comfort curve and parameter are acquired. The results can provide effective reference for helicopter cockpit steering apparatus design.
