基于操纵力感知场的人机系统操纵舒适性度量方法及优化技术

Regarding the measure and optimization of handling comfort of man-machine system as research object. Firstly, the perception field of operating force for handling comfort is constructed to map the mechanical characteristics of operating force and human physiological and psychological characteristics of the control process into the field structure for association analysis, and use a variety of human physiological and psychological characteristics parameters to characterize the handling comfort synthetically, by which the model of the perception field of operating force is built to disclose the influencing mechanism of operating force on handling comfort. Then, based on this concept, a handling comfort measurement index system is built to achieve the quantitative description of handling comfort during the control process, which consist of Base Index (based on the magnitude, angle and distance of the operating force), Volatility Index (based on the rate of the magnitude, angle and distance change of the operating force) and Accumulation Index (based on cumulative force, cumulative angle and cumulative displacement) of handling comfort. Finally, the key design factor set of man-machine system which affects the mechanical characteristics of operating force is determined and the impact mechanism of the factors on the mechanical characteristics of the operating force is quantitatively studied by analysing the dynamic and structural characteristics of man-machine system, combined with the handling comfort measurement index system, the mapping model of the key design factor set and the handling comfort indexes is established to provide theory foundation and technological support for the handling comfort optimal design of man-machine system.
