Research on Design and Analysis Method of Maintenance Operation Space Based on Hand Operations

As an important component of maintenance design work, maintenance design analysis has long faced the problem of heavily relying on equipment physical prototypes and lacking objective evaluation methods. The rise of virtual maintenance technology has gradually freed maintenance design and analysis work from the dilemma of dependence, and has also made objective and quantitative maintenance design and analysis work possible. The design level of maintenance operation space not only affects the progress of maintenance work, but also affects the safety and comfort of maintenance personnel. Therefore, it is necessary to conduct a reasonable analysis and evaluation of maintenance operation space. The previous research work still focused on qualitative evaluation and lacked innovation, which could not meet the needs of analysis work. Therefore, this article innovatively proposes the evaluation index of coverage. Based on virtual prototyping and kinematic models, the coverage of the operating space of the handheld tool and the environmental space of the target maintenance component is calculated, and the analysis and evaluation results of the maintenance operation space design focusing on hand operations are obtained. This study can provide new analytical ideas and evaluation tools for maintenance design analysis work, effectively promote the development of maintenance design work, and further improve the level of equipment maintenance.
