assignemnt代写-肋翼的制造研究

在本篇assignemnt代写-肋翼的制造研究中可以看出，在降低成本和效率的制的重点是肋翼。肋翼的制造研究将其与高成本、高损耗联系在一起。考虑一下传统的机翼加工是如何依赖于单一的铝合金坯料的(Menendez et al, 2006)。合金中大约95%的重量被加工成废料，只有剩下的部分被利用了。这导致了成本问题。使用线性摩擦焊接(LFW)技术，现在可以使用加工工艺制造翼肋，减少了材料的浪费(Li et al.， 2008)。在这里，有以张力、压缩和剪切的形式相关联的复杂载荷，必须对这些载荷进行研究，以了解整体性能的改进。不能在成本和性能之间进行权衡。接下来有关assignemnt代写-肋翼的制造研究分享给大家阅读。

In reducing the cost and efficiency in manufacturing, an important focus is the rib wings. Research on the manufacturing of rib wings associates them with high costs and high wastage. Consider how the traditional machining of the wings relied on a single billet of aluminium alloy (Menendez et al, 2006). Around 95 percent of the weight in alloy is machined off as waste and only the remaining percentage is made use of. This leads to cost concerns. The use of the Linear Friction Welding (LFW) technology now makes it possible for manufacturing wing ribs that using machining process which reduces the amount of material waste (Li et al., 2008). There are complex loadings associated here in the form of tensions, compression and shear and these have to be studied to understand overall performance improvement. Trade-offs cannot be allowed between cost and performance.

The project aims to critically analyse the strength of wing rib foot with a Linear Friction Weld LFW in the aerospace industry. A finite element method is made use of for the prediction and assessment of strength. The previous experimental data will be used to validate the FE Model.
The objectives of the research are as follows:
To present a finite element model for predicting and assessing the strength and behaviour in LFW rib foot.
To assess the LFW joint in terms of mechanical properties, requirements of the aerospace industry, and relative comparisons to other joints.
To present a valid numerical model that could be used as a base for analysing operational efficiency 。
