Numerical simulation of car crash analysis based on distributed computational environment

Automobile CAE software is mainly used to assess the performance quality of vehicles. As the automobile is a product of technology intensive complexity, its design analysis involves a broad range of CAE simulation techniques. An integrated CAE solution of automobiles can include comfort analysis (vibration and noise analysis), safety analysis (car body collision analysis), process-cycle analysis, structural analysis, fatigue analysis, fluid dynamics analysis, test analysis, material data information system and system integration. We put an emphasis on simulation of a whole automobile collision process, which will bring a breakthrough to the techniques of CAE simulation based on high performance computing. In addition, we carry out simulation for a finite-element car model in a distributed computation environment and accomplish coding-and-programming of DAYN3D. We also provide computational examples and a user handbook. Our research collects almost ten numerical automobile models such as Honda, Ford, etc. Moreover, we also deal with different computational scales for the same auto model and some numerical models of air bags are included. Based on the numerical auto model, referring to different physical parameters and work conditions of the auto model, we can control the physical parameters for the numerical bump simulation and analyze the work condition. The result of our attempt conduces to the development of new auto models.
