[Abstract]:Cloud design is a new design pattern based on cloud computing, which is multi-user and multi-domain oriented. It has become a new research hotspot in manufacturing industry to provide resources in resource pool to users by Web service according to user's demand through network. Cloud design improves the design level, shortens the R & D cycle and reduces the cost of product design. Finite element analysis is an important part of product design, but the cost of finite element analysis is high. Meanwhile, the existing remote finite element analysis research methods are mainly aimed at single enterprise or several enterprises. Deploying it to the cloud design platform solves the problem that the finite element analysis ability of small and medium-sized enterprises or even large enterprises in a certain industry is insufficient. The main work of this paper is as follows: 1. The remote finite element analysis service platform based on cloud design is built. Based on the basic principles of cloud design, this paper analyzes the key technologies of cloud design, studies the architecture and functional modules of cloud design platform based on cloud computing, and focuses on the implementation of geometric model construction and remote finite element analysis. 2. The realization process of remote finite element analysis is studied. Through the similar product feature extraction, parametric design, geometric model construction, boundary condition calibration, finite element calculation, visual output, etc. To realize the remote finite element analysis service for the key parts of similar products of the member enterprises in the industrial alliance. In this paper, the geometric model is used as the parameter input interface of finite element analysis, which realizes the consistency between product digital design and product finite element performance analysis, and overcomes the deficiency of parameterized APDL command flow file finite element operation. 3. The visual output of the analysis results is realized. Combined with the WebGL technology to analyze and process the data of the analysis result, the client can parse the data through the browser, and realize the construction of the model and the display of the cloud picture.
