dc.description.abstract | 以雷射銲接進行組裝之電子連接器,銲接品質難以預測,且其結構強度不易透過實驗進行量測。本研究藉由有限元素分析商用軟體ABAQUS,搭配自行撰寫之使用者副程式DFLUX,預測SUS304不銹鋼材料透過雷射銲接所形成之熔融區域幾何。執行拉伸與剪切試驗,檢視單一銲點之銲接強度於不同負荷型態下之破裂情形。透過數值分析,導入前述預測銲點熔融區域模型與材料性質,配合延性與剪切破裂準則,進行拉伸與剪切試驗模擬,並根據實驗量測結果,調整損傷演化相關參數。最終將本研究分析流程應用於電子連接器金屬外殼銲接件,進行其結構強度分析,藉以提供電子連接器相關產品設計與改良依據。 | zh_TW |
dc.description.abstract | Characteristics of the pulsed laser spot-welding applied to electronic connector industry are investigated in the current study. A user subroutine DFLUX integrated in the commercial finite element package ABAQUS is coded to evaluate the weld pool profile of 304 stainless steel sheets under various laser intensities. Bead shapes including the pool diameter and the penetration depth as well are predicted and compared with the associated experiments. Two different stainless steel samples subjected to tensile and shear conditions are conducted to assess the loading capability of welded joints. Both ductile and shear damage criteria are implemented into the numerical analysis to account for the failure of the spot welded structure. Plastic behaviors of the weld pool of the metal are estimated based on the corresponding hardness test. Strength of a metallic shell welded with the electronic connector structure is then examined, and results based on the simulation are in fair agreement with those based on the measurements. Efficient layout of the welded locations is finally advised. | en |
