Composite material part curing deformation compensation design method based on finite element simulation

The invention discloses a composite material part curing deformation compensation design method based on finite element simulation, which comprises the following steps of: establishing geometric models of a composite material part and a forming tool thereof, and carrying out finite element simulation calculation by assigning material characteristics of the composite material part and the forming tool thereof; and according to a finite element calculation result, a node displacement method is used for carrying out compensation design on a composite material part molded surface node, and a compensated mold geometric molded surface is directly calculated, so that accurate compensation design of the composite material molded surface is realized. According to the method, an inverse iterative optimization method is adopted, an optimized forming surface is formed through inverse compensation of node displacement, springback compensation of a complex molded surface is very convenient and feasible, molded surface node
