Research on distributed cooperative CAE analysis platform construction

Based on requirements analysis of distributed cooperative CAE, this paper proposed a distributed cooperative CAE analysis platform architecture, which has four functional modules and uses a three layered architecture: user layer, logic layer and data resource layer. Some key techniques used in the platform were discussed, including cooperative CAE analysis tools, cooperative CAE management tools, CAD/CAE integrated modeling techniques considering the finite element analysis features in CAD model, optimization method of operating speed and network security of the platform, which uses a multi-layered security architecture based on IP security protocol (IPSec), virtual private network (VPN) and security socket layer (SSL). The above-mentioned techniques support the distributed cooperative CAE analysis platform construction and operation.
