Research of Holographic Assembly Technology for Overhead Traveling Crane’s Bridge Based on the Holographic Model

According to the crane’s bridge structure assembly characteristics, taking advantages of 3D CAD software about “top-down” parameterization model design, importing the concept of product holograph assembly, all-purpose distortional module was established. Adaptive architecture based on holographic assembling and knowledge reuse was constituted ,through renewing and reusing the distinct assembly module knowledge, which used “Layout Sketch “controlling the assembly parameter and adopted the constraint relation of holographic model realized the product design alteration. The results show that the technology has satisfied the needs for assembly knowledge reuse of the products variant design, to greatly enhance product knowledge inheritance.
