Grid applications middleware system facing distributed automobile safety synergic design

Abstract

The invention discloses a grid application middleware system facing to a distributed automobile safety collaborative design, comprising: a finite element model assembling service module, a simulation monitoring service module, and a result analysis service module. The finite element model assembling service module dynamically assembles CAE module provided by all parties participating in the collaborative design, so as to finally form a whole vehicle CAE digital model which can be solved. The simulation monitoring service module realizes a finite element calculation function of vehicle crash, a calculation course controlling function, a calculation detecting function and a finite element module verification function. The result analysis service module realizes a resolution function for crash result. The three modules are associated with each other, or run separately. The invention hides key technologies via reasonable division for the whole finite element model and an extraction technology of solving result, so as to solve out cooperating with a security requirement of all parties for intellectual property.

Description

Technical field [0001] The invention relates to a system in the field of computer application technology, in particular to a grid application middleware system oriented to distributed automobile safety collaborative design. Background technique [0002] With the popularization of global production forms, collaborative design between vehicle manufacturers and component manufacturers has become a common concern among automobile manufacturers. Especially the safety design of automobiles. This type of design mainly involves the CAE (Computer Aided Analysis) analysis process, and CAE modeling technology is the intellectual property that cooperates with all parties to protect, on the one hand, it is because of the finite element model for crash safety simulation. Contains a lot of information that needs to be kept secret, such as modeling techniques, material constitutive relations, and vehicle geometric information. In addition, when a component supplier is cooperating with multiple O...

[0004] After searching the literature of the prior art, it was found that Gerlicher et al published the article "A Framework for Real-TimeCollaborative Engineering in the Automotive Industries" ("Real-Time Collaborative Architecture of Design", Proceedings of the International Conference on Collaborative Design, Visualization and Engineering, 2006: 164-173), the collaborative architecture proposed in this paper using CSCW (Computer Supported Cooperative Work) Sharing, when the parties involved in the collaboration have confidentiality requirements for their model information, obviously, this architecture is not suitable

And this architecture is only aimed at the field of automotive electronics design, and does not support relatively complex CAE collaborative design
