Abstract

An important role a landing gear plays is that it aids in the landing and takeoff of aircraft. The landing gear must be designed in such a way that it can take these stresses in static and dynamic situations. This is to accommodate both rough and smooth landings that result from various loads acting upon it, such as drag force, vertical load, and side load. In the aviation industry, landing gear stress is a key concern, and different research in this field has previously yielded excellent results. However, the time has come to raise the bar even higher. This report will focus on the optimization of the Boeing 777's nose landing gear to better withstand rough landings. During the timeframe of this research, SOLIDWORKS was utilized to model and analyze various components of the landing gear. The results summarize that a single material should be avoided throughout the components of the landing gear. Components such as pistons with a larger stress allocation should be made of titanium alloy, while components with a lesser stress allocation should be made from aluminum alloy.Abstract.

波音777前起落架的特性，以更好地承受粗糙着陆

起落架的一个重要作用是帮助飞机起降。起落架的设计必须使其能够承受静态和动态情况下的压力。这是为了适应粗糙和平滑的着陆，由不同的负载作用在它上，如阻力，垂直载荷和侧载荷。在航空工业中，起落架应力是一个关键问题，此前在这一领域的不同研究已经取得了优异的成果。然而，是时候把标准提高得更高了。本报告将重点关注波音777前起落架的优化，以更好地承受颠簸着陆。在本研究期间，SOLIDWORKS被用于对起落架的各个部件进行建模和分析。结果总结，单一材料应避免在整个起落架的组件。应力分配较大的活塞等部件应采用钛合金制造，应力分配较小的部件应采用铝合金制造。起落架的一个重要作用是帮助飞机起降。起落架的设计必须使其能够承受静态和动态情况下的压力。这是为了适应粗糙和平滑的着陆，由不同的负载作用在它上，如阻力，垂直载荷和侧载荷。在航空工业中，起落架应力是一个关键问题，此前在这一领域的不同研究已经取得了优异的成果。然而，是时候把标准提高得更高了。本文将重点介绍波音777前起落架的改进，以更好地承受颠簸着陆。在本研究期间，利用SOLIDWORKS 2020(独立许可)中的运动研究对起落架的各个部件进行建模和分析。结果总结，单一材料应避免在整个起落架的组件。应力分配较大的活塞等部件应选用钛合金，应力分配较小的部件应选用铝合金。

期刊介绍： "International Journal of Engineering Research in Africa" is a peer-reviewed journal which is devoted to the publication of original scientific articles on research and development of engineering systems carried out in Africa and worldwide. We publish stand-alone papers by individual authors. The articles should be related to theoretical research or be based on practical study. Articles which are not from Africa should have the potential of contributing to its progress and development.
