燃料電池混合動力車複合材料車體結構設計方法之研究

The Design Method of CompositeBody Structure for Fuel Cell Hybrid Vehicle

指導教授 : 鄭榮和

摘要


為了減低車輛上能源的消耗,使用先進複合材料製造之輕量化車體結構將有可能成為未來車輛的發展趨勢。本研究提出兩階段的設計方法:(1)修正演化式結構最佳化方法(Modified ESO)與(2)以“剛性效率增量”做為複合材料厚度增減與修正順序判準的設計方法;來解決複雜的複合材料車體結構之設計問題。同時藉由台灣大學機械系—燃料電池混合動力車研發計畫的執行,將本研究提出之設計方法應用於其車體結構設計上,檢驗設計方法之可行性。研究證明,透過此二階段之設計方法確實可以設計出符合需求且性能優異之車體結構。

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.
