| Abstract: | To improve the durability for automobile, virtual iteration is performed by inputting the data obtained by automotive road tests, including acceleration, displacement stress and so on. The automotive body fatigue analysis and optimization are performed by inputting the virtual iteration results such as force and moment of automotive body attachment points, and the durability reaches the reliability goals. |
