Abstract: Human errors are caused by unreasonable ergonomics design mostly. There are various ergonomics design and evaluation methods. However, traditional ergonomics evaluation methods are the absence of efficiency and convenience. This paper focuses on building a novel ergonomics method for system design and evaluation. This method enables to establish virtual circumstances, create a manikin model, assign the manikin to complete relevant tasks and perform man-machine ergonomic analysis in the process of task execution based on the software JACK. The ergonomic analysis includes dynamic spatial accessibility analysis, visibility analysis, working posture analysis and predicted time of completing tasks. This method has been vitrificated and validated by the task of rotating the left and right handles in the working scenario. Also, this method can be typically used to analyze and judge whether the human, machine and environment system is harmonious. In comparison to traditional methods, this method is given access to shorten the design cycle, reduce the research cost and improve the research efficiency.
