Abstract

The invention discloses a virtual assembly simulation method and system, relates to a method and system for visual assembly of a product model, and aims to solve the problem that in the existing design, the matching size of product parts tends to deviate when function and size design is carried out firstly, and assembly verification is carried out through a physical product then. The method comprises the following specific steps: S1, importing an assembly model; S2, generating a first assembly sequence according to the complete assembly model; S3, performing visual operation on a part model by using the virtual tool and a reference assembly sequence, and generating a second assembly sequence; and S4, optimizing and updating the second assembly sequence by using an assembly process optimization algorithm, replacing the original reference assembly sequence with the updated second assembly sequence, and returning to the step S3; or finishing assembly, and ending virtual assembly simulation.

Description

technical field [0001] The invention relates to a method and system for visually assembling product models. Background technique [0002] At this stage, the processing and manufacturing industry relies on CAD / CAM software to realize rapid product design, automatic and integrated processing. However, the assembly of the product still adopts the method of designing and processing first, and then using the actual product for assembly verification, and the assembly efficiency is low. Especially complex products (such as airplanes, automobiles, etc.), are usually developed by cooperation between multiple departments or companies. The existing design generally first designs the function and size of the parts, and then performs assembly verification on the physical product. Pre-design and post-assembly are relatively independent, and assembly and design cannot share data. If these departments or development companies do not communicate well, it may cause deviations in the matchin...
