This application is a numerical-computation-based digital R & D method and
system for the lightweighting of power tools, belonging to the field of
power tool optimization. Aiming at the obvious limitations in the R & D of existing table saw power tools, a numerical-computation-based digital R & D method for the lightweighting of power tools is provided: According to the division of functional roles and connection relationships, table saw power tools are disassembled into different functional components; Standardized
functional analysis modules for each functional component are constructed based on the finite
element analysis method; A digital 3D model of the functional components of the table saw
power tool is obtained, and the surface feature information and load parameters obtained by the interaction of the corresponding functional components are set. By outputting the stress, strain, and deformation data of the corresponding functional components and converting them into the corresponding cloud map results. This application modularizes each functional component of the
power tool, can adapt to and verify different application scenarios and
customer requirements, reduce the difficulty of pre-
processing settings for finite
element analysis, and can also reduce costs and technical thresholds and shorten the R & D cycle.
