碩士 === 國立臺灣大學 === 機械工程學研究所 === 94 === In order to lower the power consumption on the vehicle, using advanced composite light weight car body structure might become the tendency of future vehicle development. This thesis brings out a two-stage design method in the design of composite auto body structure. Firstly, adopt Modified Evolutionary Structural Optimization (Modified ESO) in the primary design; then apply “stiffness efficiency increment” to be the criterion to revise the thickness and layer orders of composite sheet layout. The method is derived to solve the design problem of the complicated composite car body structure. This two-stage design method is applied to the car body structure of the fuel cell hybrid vehicle of mechanical engineering department of National Taiwan University to verify its feasibility. The result shows the two-stage design method is indeed able to achieve the design goal of rigidity demanded under the vehicle application and still maintains advanced light weight and sporty performance for cars.
