中文摘要

本文針對摩擦攪拌銲接方法進行研究,透過對基礎銲接參數特性研究,進而深入探討銲接參數與機械性能及銲後變形量的關聯作用,建立可精準預測銲接變形量的參數設計方法,同時導入TRIZ設計方法協助進行創新設計,提供作為銲接設計者進行銲接製造時誘發創新靈感之設計工具。本文中首先對摩擦攪拌銲接方法與特性及TRIZ整合設計方法概述外,主要研究項目有三階段。首先進行「摩擦攪拌銲接銲接基礎參數與眾不同機械性能分析研究」,針對摩擦攪拌銲接銲接適用之鋁合金材料進行基本銲接參數特性研究,透過不同機械性質如抗拉強度、硬度、斷面組織等的基本性能分析,建立可行的銲接區域(welding zone);隨後進行「銲接參數與變形量關係特性研究」,透過適當的銲接參數實驗,提出銲接參數與銲後機械強度、收縮變形的量化關係,建立可預測銲接性能的設計方法。透過此特性設計研究,將銲接製程的變形因素予以量化。建立的研究資料可作為製造設計時尺寸公差或後續精加工量訂定之參考依據,此一研究並在案例的實施上獲得驗證。
同時為達到有效並可預期的銲接效果,摩擦攪拌銲接銲件的固定與挾持定位設計對銲接品質極為重要,也欠缺可參考之設計資料。因此本文導入TRIZ設計方法與缺乏矛盾訊息之設計方法,並整合建立解決設計問題的流程模式,協助設計者在缺乏相關製程經驗或面臨技術瓶頸與衝突時,藉由TRIZ工程參數與創新法則組合,可從不同方向思考並獲得有效之建議。透過實務案例的推演分析與應用獲得具體可行之驗證。

英文摘要

The article is focused on friction stir welding method. Through basic welding parameter characteristic study and thoroughly study the connections between welding parameters, mechanical properties and welded distortion. Establishing a parameters design method can be used to precise predict welding distortion. TRIZ design method is conducted to assist innovative design and provided as a design tool to inspire innovative idea when the welding designer executes welding manufacture.
In the beginning, the article briefly introduces friction stir welding method and characteristics and TRIZ integrated design method. Main research item is divided into three stages. In the first place, the research conducts Basic study on Mechanical Property Analysis of Friction Stir Welding to focus on basic welding parameter study on aluminum alloy applicable to FSW. Through mechanical property analysis, such as tensile strength, hardness and section structure, the research establishes feasible welding zone and realizes characteristics of different parameter in depth. Afterwards, the research conducts Parameter characteristics Design Study . By proper welding parameter experiment, the research proposes quantification relations among welding parameter, as-welded mechanical strength and shrinking deformation and establishes the reliable parameter combination to predict weldability. Optimal design study can quantify welding deformation factors. Established research data can serve as reference to design of size tolerance or setting of subsequent precision machining volume. The research acquires verification through case implementation.
To achieve effective and predicable welding result, fixation and clamping design of work piece in the friction stir welding plays an important role of welding quality. However friction stir welding is lack of above related data as design reference. The article therefore conducts Innovative Design Case Study of TRIZ in the Friction Stir Welding to introduce TRIZ design method and design method in lacking of contradicting message and establish process mode to solve design problems. Lacking of the related manufacturing process experience or facing technical bottleneck and conflict, the research assists the designer to consider from different angle and acquire effective suggestions through combination of TRIZ engineering parameter and innovative principle. Finally, the research can acquire concrete, feasible verification through analysis and application in different cases.
