摘要
本研究主要是建立汽機車卡鉗結構輕量化及設計之流程，研究中以汽機車卡鉗作為研究對象，並採用ANSYS Mechanical有限元素分析軟體(FEA)及拓樸最佳化分析(Topology Optimization)的方法進行拓樸最佳化設計。 本研究先假設一個符合設計布置的長方體卡鉗作為起始設計，經由拓樸最佳化軟體進行2~3次分析，再使用有限元素模型，進行卡鉗結構強度分析、疲勞壽命分析、模態分析。在分析結果顯示，在設計當中給予條件後可以設計出滿足這些條件的拓樸結構模型，其應力值均在容許應力當中，符合強度需求。從疲勞壽命結果顯示，基於Miner累積損傷理論進行結構損傷之預測，判斷發生位置及損傷壽命，設計的汽機車卡鉗符合JASO C448-80規範，滿足疲勞設計之要求。最後再以模態分析探討輕量化後自然頻率的影響。 研究結果顯示：經由拓樸最佳化後的卡鉗達到良好的輕量化效果，與市面商業化的產品也具有類似的形狀與強度。此分析技術可應用在卡鉗設計驗證的階段，建立設計卡鉗分析流程之技術，有效減少卡鉗研發所需的時間、減少試作與測試次數。

This research is aimed to establish the lightweight design and process of the caliper structure of automobile and motorcycle. In this research, the calipers of automobile and motorcycle are taken as the research object, and the topology optimization and structure strength design is carried out by using the ANSYS Mechanical finite element software and Topology Optimization modulus. In the beginning, this study assumes a rectangular caliper that fits the design layout served as the starting design, performs 2~3 times analysis through the topology optimization software, and then uses the finite element model to perform caliper structural strength analysis, fatigue life analysis, and modal analysis. The results of the structural analysis show the stress values of caliperare among the allowable stresses and meet the strength requirements. From the fatigue life results, the prediction of structural damage based on Miner cumulative damage theory is used to judge the damage life of the location. The designed locomotive calipers conform to the JASO C448-80 specification and meet the requirements of fatigue design. Finally, the modal analysis is used to investigate the effect of natural frequency after light weighting. The results of the study show that the calipers optimized by the topology achieve a good weight reduction effect, and have similar shapes and strengths compared with commercially commercial products. This analysis technology can be applied in the stage of caliper design verification and establishes the technology of designing the caliper analysis process, which effectively reduces the time required for caliper development and reduces the number of trials and tests.
