基于CAE的汽车前舱盖及后背门垂直刚度的模拟分析

Perpendiculer Stiffness Analysis of the Front and Rear Cover of Vehicl Based on Computer Aided Engineering (CAE)

如何提高汽车的安全性,如何预先得知汽车安全性的高低,是现在汽车设计时的重点。由于计算机高速发展,以及计算机辅助设计(CAD)的兴起,使得汽车设计的效率和精确性有了质的飞跃。而计算机辅助工程(CAE)的出现,可以使设计人员在计算机的虚拟环境下进行汽车刚度强度等等安全性分析,模拟各种碰撞,为实车的安全性打好基础。

:Now,how to improve and anticipate level of the vehicle safety is the focus of vehicle design.With the rapid development of computer and the emergence of computer aided design (CAD),the efficiency and accuracy of vehicle design have tremendous progress.The designers can use the Computer Aided a Engineering (CAE) to analyse the safety of stiffness and strength etc and simulate the collision in the virtual environment.
