New layout design of hard sleeper carriage in regular speed train
To improve comfort and safety of passengers in hard sleeper compartment of regular speed train,the human-machine scenario of passengers'sitting posture,luggage placement in high places and climbing stairs,as well as the simulation analysis results from the ergonomic software Jack,it was found that the 25G hard sleeper compartment could not meet the sitting rest of passengers in the middle and upper berth.The ease of use and safety of luggage racks and climbing stairs were poor.The design improvement scheme was determined based on the corresponding problem-solving tools of physical conflict,technical conflict and matter-field models in TRIZ.Man-machine rationality and analysis were carried out to check the improved scheme.The improved hard sleeper compartment increased the height of middle and upper berth sitting space,and reduced the height of the upper baggage storage area,meeting the requirements of the passengers at different percentiles in the upper berth sitting position and personal baggage storage.The blind area of the pedal-visual field and the RULA comfort rating were reduced during passengers climbing.The accessibility of berth armrests and upper limb comfort were improved during climbing.
