Ergonomics evaluation of the main pilot's seat for the full ocean manned submersible
To meet the requirements of safe and efficient deep-sea operations of manned submersibles in full ocean depth,a comprehensive analysis was conducted on both the internal and external factors that significantly affect the operational efficiency.The operational characteristics of the manned cockpit within a complex human-machine-environment system were discussed.The principle of human-centered should be maintained in the human-machine-environment.A ergonomics evaluation method of main pilot's seat was proposed based on a multi-parameter coupling approach integrated physiological and psychological factors through the comfort analysis of submariner in the manned capsule of a deep-sea manned submersible.The results indicated that the main pilot seat of a full ocean depth manned submersible could potentially lead to increased levels of muscle fatigue,heightened anxiety,and a general decrease in comfort for the pilot.The comfort of pilot in the confined cockpit space could be effectively alleviated through the adjustement of Seat lumbar angle.The main pilot seat equipped with a lumbar support unit in manned submersibles should be comprehensively considered in human-machine-environment factors.The deep-sea diving operation performance of the pilot was enhanced further.The multi-parameter coupled ergonomic evaluation methods could provide references for the future optimization design of manned submersible seats.
