Description

technical field [0001] The invention relates to the field of high-precision product assembly, in particular to a product digital twin model simulation method and system. Background technique [0002] High-precision products are widely used in aerospace, marine, automotive and other systems, and are the core components of the system. High-precision products have many assembly components, complex assembly process and high assembly precision requirements, and there are complex nonlinear relationships between their input and output. Traditional virtual simulation is mainly used in the assembly design stage. Virtual simulation is performed under the established ideal geometric model to obtain assembly paths, assembly sequences, and analyze various assembly performances. However, the assembly process obtained through the simulation of the ideal geometric model is usually relatively rough, and there is a large discrepancy with the actual assembly process parameters, and the simula...
