Research On The Human Compatibility Design Theory And Method Of High-Speed Train Driving Interface

Driving interface of High speed train is a workspace where drivers can not only receive messages, make decisions and control commands for related systems, but also accomplish driving task and any other kinds of tasks. Whether the design and arrangement of the display and operation devices are scientific or not will be a great impact on how the drivers achieve his driving functions completely and accurately. So it has important theoretical value and practical meaning to study the human design theory and method for driving interfaces. Starting from the driving tasks analysis, this dissertation studied the driving manipulative patterns, and then constructed the compatibility model of the driving interface. And at last, it put forward a dynamic assessment method of human compatibility for driving interface, which is a kind of theory base and method support for the design of driving interface.The definition of operation of train-driving was proposed first, then basing on the human information processing model and using the comprehensive hierarchy analytical method and cognitive task analytical method, this dissertation proposed and constructed a driving task analytical model of high-speed train drivers. Base on this tool, the driving task categorization model was accomplished for the normal driving task. Driving task was divided into monitor task, mental task, adjustment task and communication task, and all tasks were divided into functional layer and interface layer.The relationship between the interface layer corresponding task model and the operation compatibility in driving cab were analyzed. Basing on the generalized motor programs, the operation mode theory was brought up. Then all the following rules were defined:operating resources mapping rule, operating task filter and escape rule, operating form rule, operating time rule and operating space rule. On this basis, the flexible constructing driving platform of human factors research was built, and the marking system of upper body in sitting driving posture was developed. The design and implementation of the operating mode experiment was completed, and the experiment data were processed and analyzed. All the results validated the consistency of right- and left-handed operation in the driving circumstance. The operating time rule, the velocity distribution rule and the operating track rule were achieved. And in final, each rule's definition formula was proposed.The compatibility model of high-speed train driving interface was constructed, which consisted of three main parts:the High-speed driver's human model, the driving interface products model and the compatibility prediction model basing on inverse kinematics. The compatibility model can predict the position and posture of the drivers who would achieve the driving tasks on the diving interface, and it would lay the first stone for the evaluation and analysis of the interface's suitability later. In the research of the inverse kinematics solving, a brand new solution algorithm of HAL chain basing on minimum change of dihedral angel was proposed by analyzing the motion characteristic of human body in high-Speed train driving. This algorithm was popularized to resolve the posture relations among elbow joint, shoulder joint, collar joint and neck joint.Three basis requirements of driving seat on high-speed train was concluded and put forward, which were geometry compatibility requirement, safety requirement and labor protection requirement. On this basis, the evaluation method on suitability driving seat design which was based on distribution range of comfortable H-point was proposed. The dynamic evaluation method of the geometry compatibility for the driving interface was brought up, too. According to the driving operating task pattern and the driving mode theory, this method achieved the prediction on the operating posture through driving operating mode sequences and the high-speed driving interface compatibility model. Basing on the evaluation criterion of Rapid Upper Limb Assessment (RULA), this dissertation accomplished the assessment of the geometry compatibility for dynamic driving operation.By giving demonstrations on the high-speed train driving interface of CRH3C and CIT400, this dissertation accomplished the assessment and contrastive analysis of the driving seats and interfaces'geometry compatibility between the two examples using the human geometry compatibility theory and method. For the CRH3C, this dissertation assessed the driver's postures using observation method in the same condition. And the results verified the reliability and validity of the prediction method on human compatibility for driving interface.
