| Abstract: | Composite sandwich structures are now used extensively in aerospace,automotive and civil infrastructure due to its main advantages of high strength,high stiffness and lightweight.On the basis of the analysis of the sandwich structure subjected to single constraint,a lightweight design is done for the single-constrainted sandwich structure by taking the chassis deck of one electricity motorcycle as an example.The results show a good lightweight design to ensure vehicle stability. |
