摘要 以當前的汽車零配件市場來說,鋁合金輪圈在近十年來的發展,可說是變化巨大,且競爭激烈,不論是在技術的引用與市場的開拓,各製造廠皆各展其能,其中又以技術研發為一發展之重點。 本研究係以當前鋁合金輪圈開發最被熱烈探討的FEM為主軸,利用CAE軟體,進行對鋁輪圈13度衝擊試驗的分析與實物探討,用以研究CAE軟體對解決鋁輪圈開發上最為困擾的結構設計問題的可能性。 本研究以目前先進的3D CAD軟體,設計與實物相同的模型,再以CAE軟體切割細密的MESH模型,配合實物試驗的模擬,進行解析。解析完成之結果再搭配實物實作試驗的比對,達到理論與驗證之效果,而所得到的比對結果,正如我們所預期。 以整體而言,本研究對產業有實質的效益,這也是本研究的主要目的之一,然而,若要使FEM技術發揮更大的效益,使CAE能夠在鋁輪圈的開發上扮演重要的角色,則應進行更深入且長期的研究。
ABSTRACT With regards to the current autoparts market,aluminum wheel is the part with a huge change and the competition among manufacturers has been very keen for the past decade。Every manufacturer does its best in using new technologies and expanding its market share。R&D is the most important key point of them all。 The focus of this research is to utilize the most advanced 3D CAD software to design an aluminum wheel and use the CAE software to simulate the aluminum wheel under 13 degree impact test 。By comparison between the simulation results and experimental data,we found the CAE simulation is valuable in aluminum wheel design。 However,if we want to make CAE simulation more effective and enable CAE to play an important role in developing aluminum wheels,we should proceed and engage ourselves in long term research。
