Abstract: A task-structure-iteration fusion design method is proposed to improve the experience of operator manipulating mining excavator and the operation interface design. Questionnaire, field investigation and literature analysis are carried out to investigate the operator perceptive status to environment and information in the task and to find out the shortcomings of the existing operation interface, and the design points aiming at the defects are obtained. The mapping between modules and the design points is established by dividing the layout of operation interface into several modules with a structure split method. The arrangement methods of the console, control panel and control components are developed, with shading and anti-misoperation considered. The engineering software Jack is used to iteratively evaluate the visibility, accessibility and comfortability of mining excavator operation interface. The results show that the rationality of the operation interface is improved by the task-structure-iteration fusion method.
