Abstract
This research focuses on ultra-high specific stiffness and strength composites sandwich car structures. The topics include material selection, analytical evaluation, experiments, highly efficient and automatic optimization tools, and detailed insert design. It aims to construct complete and systematic design procedures to deal with complicated composites structures. It firstly compares practical face and core materials for selection references, and summarizes experiments and analytical optimization methods for simple beams or plates. The whole body structure optimization is then carried out with a novel algorithm-ESSO (Evolutionary Sandwich Structural Optimization) and an equivalent shell element. The proposed optimization method can efficiently find out best material combinations to fulfill tough stiffness and strength requirements for various driving conditions. Besides, it developes detailed design methods for sandwich structure weakest points, where concentrated loads applied. Two successful design examples-the third generation solar car and the first generation fuel-cells hybrid car of Mechanical Engineering Department, National Taiwan University demonstrate efficiency and accuracy of the proposed design and optimization procedures. In conclusion, this research provides an effective way for designers to design a highly efficient green car or a high-performance sports car that expects an extra-low weight structure.
