Method for realizing flexible cable assembling model in virtual assembling environment

Abstract

The invention discloses a method for realizing a flexible cable assembling model in a virtual assembling environment according to the application requirements of cable assembling process design and verification in the field of virtual manufacturing. In the method, the cable assembling model is divided into a cable branch model and an electric connector model and the method is implemented by the steps of CAD design information read, model information architecture in the virtual environment, real-time assembling operation and the like, wherein the cable branch model can realize real-time flexible deformation according to a loaded mass spring system and perform clamping assembling operation by setting the attribute of the mass point; and the electric connector model can realize the cable assembling operation such as plugging and the like according to a restraining model. The method adopts the design information of the cable and overcomes the defect that the conventional cable assembling process design and verification depend on a physical model heavily on the premise of not changing cable design parameters. The method has the characteristics of obviously improving the efficiency of product assembling design and reducing design cost, along with accurate model, good intuitive performance and interactivity.
