| Abstract: | Frame reliability is essential for truck safety.The finite element model of a light duty truck frame was established using CAD/CAE technology.Modal analysis of the frame was made.The first eight-order natural frequencies and corresponding vibration modes were obtained.Random road spectrum responding analysis was used to ascertain the dynamic characteristic of the frame.The results indicate that the analysis enables the improvement of stability,comfortability and security of the automobile. |
