According to the characteristics of aerospace product, the model representation and storage of the rigid part and cable harness is proposed. The Dendritic Correlative Model of Mixed Assembly of Rigid and Flexible Parts (DCMMA-RFP) is introduced based on the hierarchical model and graph model. The assembly model which realizes the lightweight storage can clearly represent the hierarchy relation and assembly process of aerospace products. The assembly modeling process in the virtual assembly environment is detailed described. Finally the effectiveness of DCMMA-RFP is verified by an example.

The micro-topographic quality of a product’s surface directly affects the performance of the virtual assembly. The computational precision of the fractal dimension has a significant effect on the accuracy of the virtual assembly model. To address the imprecision and large deviation of the calculation method under some conditions, a virtual product assembly surface modeling method is proposed in this article based on the root mean square of the area residuals. First, the fractal dimension of the surface is calculated using the regional residual root mean square (3R method). The feasibility of the 3R method is verified by comparing with the existing methods on isotropic and anisotropic surfaces. Second, the fractal dimension of a real part surface is obtained using the 3R method. According to the Weierstrass–Mandelbrot function, a partial surface model of the machined part is established. The surface contours, roughness, waviness, and flatness of the part are extracted by wavelet transform. Then, the digital surface model for virtual assembly with the same profile parameters is generated by reconstructing the surface contours of the actual parts. Finally, the method proposed by taking the virtual assembly of a VTM200/F5 turn-milling composite machining center guideway is verified in this article.

Design For Assembly/disassembly (DFA) allows systematic evaluations and analysis of product assembly and disassembly during the product design stage with the goal of reducing assembly costs, improving quality and shortening time to market. These evaluations include assemblability, disassemblability, part accessibility, and part layout [1]. With the growing availability and widespread use of high bandwidth network and Virtual Reality (VR) technologies, the issues involved with product assembly, disassembly may be addressed and resolved effectively in a collaborative virtual environment over the Internet. In this paper, an analysis on the framework and definition of a collaborative virtual assembly and disassembly system, called Motive3D [2, 3], is introduced and examined using Unified Modeling Language (UML) [4]. UML is an Object Management Group’s (OMG) standard for object-oriented analysis and software design method, which allows specifying, constructing, visualizing, and documenting a distributed software-intensive system. Carrying out systematic analysis on the Motive3D system using UML, we believe that it expedites system development and will be possible to expedite the product design cycle and enable the assembly and disassembly process over Internet, and thus reduce the assembly and disassembly process bottlenecks.

Aiming at the current situation that there is lacking in-depth study on applications of virtual technology in mechanical manufacturing and assembly process control, the virtual assembly systems was researched and designed based on combining virtual reality technology with mechanical assembly process. The support mechanism of virtual assembly platform was designed based on taking shaft parts as example, and modeling method of 3D features parameters was adopted in order to build the model of virtual assembly parts, which was modeled according with the sequence as describing physical feature parameters of parts, building data structure of feature parameters and building model features library. On the basis of modeling virtual assembly platform, the key technologies of realizing the virtual assembly processing, which was from positioning issue and collision detection issue, were also analyzed, and control methods of virtual assembly processing were pointed out in detail. All is work is significative for enhancing the level of virtual technology applications, digital machinery manufacturing and assembly.
