代写论文：航空航天焊接技术
更好的减重和性能是航空制造业工程业务的核心。在机翼肋，风扇，压缩机转子等的制造和设计中，对制造效率的需求增加，这有助于实现性能和成本效益。在传统的制造方法中，正在使用锻造材料，然而这种锻造材料的形式并不高效，因此将焊接技术的分析纳入其中。线性摩擦焊（LFW）是本文的分析对象。这是一种已经在航空航天制造中使用的焊接技术，例如压缩机叶片等.LFW是一种固态焊接技术，其中焊接表面被摩擦在一起使它们升温（Wanjara＆Jahazi，2005） 。目前的研究试图了解使用LFW模型来实现更好的运营效率的可行性。二维有限元模型方法用于这种分析。

Better weight reduction and performance is at the core of operations in engineering of the aerospace manufacturing industry. In the manufacture and design of the wing ribs, the fans, the compressor rotors etc., there is an increased need for efficiency in manufacturing that could help achieve the performance and cost benefits. In traditional manufacturing methods, forged material was being used however this form of forged material is not efficient and this brings into context an analysis of welding techniques. The Linear Friction Welding (LFW) is the object of analysis in this work. This is a welding technique that is already being used in much aerospace manufacturing such as compressor blisks etc. LFW is a kind of solid state welding technique in which the weld surfaces are rubbed together to cause them to heat up (Wanjara & Jahazi, 2005). The current study attempts to understand the feasibility of achieving better operational efficiency using the LFW model. A 2D finite element model method is used for this analysis.
