The invention discloses a virtual maintenance simulation automation generation method and device and relates to the virtual simulation technology field. The method comprises steps that semantic analysis and identification for a to-be-simulated maintenance procedure are carried out to acquire each key characteristic of the maintenance procedure reflecting a maintenance process and operation; the each key characteristic is inputted to an established maintenance procedure expression model based on the key characteristics to acquire the expression information of the maintenance procedure; simulation tools respectively corresponding to each key characteristic are searched from a simulation tool set; the maintenance procedure expression information and the simulation tools are utilized to generate a virtual maintenance simulation process of the maintenance procedure. The method is advantaged in that through carrying out regular summary and application for personnel operation of the maintenance procedure, repeated work of virtual maintenance simulation taking the maintenance procedure as a reference basis is reduced, virtual maintenance simulation efficiency is improved, and technical feasibility is provided for automatic and intelligent development directions in the virtual reality field.
