The invention provides a standardized design method for an electric power tool model of a VR electric power training system. The standardized design method comprises the following steps: (1) collecting electric power tool structure data and carrying out three-dimensional modeling; (2) roughly splitting the three-dimensional model of the electric power tool for the first time; (3) carrying out secondary rough splitting on the obtained unit structure; (4) finely splitting a unit structure; 5, constructing a three-dimensional model sample library; 6, training the data sample library: training thedata sample library by adopting a linear fitting method; and 7, building an electric power tool model. According to the method, a standardized three-dimensional model database established by an existing electric power tool is used as a design basis, and when the electric power tool of the VR electric power training system needs to be modeled, modeling of various different electric power tools canbe completed only by calling the database, so that time and labor are saved, and the design efficiency of the VR electric power training system is improved.
