MODIFY INTEGRATION ALGORITHM BETWEEN CONTROL SYSTEM OF PART LIFE CYCLE AND VIRTUAL DESIGN PLATFORM
Abstract
The low hardware and software development success is a problem in CAD. The problem entails large expenditures of material, technical and human resources. In order to increase the product development success need to solve the issue of integrating virtual prototypes in the design stage. The issue includes a digital representation that allows evaluate the design's operability. The paper describes the integration between LOTSMAN:PLM and Unity 3D, that includes the modified algorithm development for searching and extracting 3D assemblies in the repository. This algorithm has a name api.getinfo, that allows to aggregate design, technical and operational information. These information puts into a query to extract a 3D assembly for a graphical repository. A specialist can estimate the assembly ergonomics in virtual reality. At industrial enterprise computational experiments were carried out with a modified algorithm implemented like an integrator of 3D assemblies into virtual reality. 3D assembly’s examples were obtained in a graphical repository. A specialist can estimate the location of working bodies and blocks in virtual reality. The integrator interacts with products from ASCON, SolidWorks, AutoCAD, Altium Designer and Delta Design.The modified algorithm reduces the time required to build, evaluate, and edit a 3D assembly by 10% (1.25 business days). Results are based on the experiments. The integrator is embedded in a design and industrial enterprise and in training (advanced training, retraining) of specialists. The work uses a set-theoretic justification for mathematical description of expressions, parameters, etc. Further research is related to the identification of errors in the behavioral specialist model
