GH4169高温合金仿真研究机械设计制造及自动化专业

摘要当处于高温环境下，镍基高温合金 GH4169 依然能够保持高强度以及良好的稳定性。正因如此，其才在航空领域以及军事领域中，获得较为广泛的实际应用，然而，因为其在加工时的硬点不佳，并且无法保证较为良好的导电性，故而难以进行加工，也由此限制其自身的多方位应用。因此，针对镍基高温合金所含的切削性能以及切削时表现出的切削力改变，进行较为深入的细致剖析，将有助于选择恰当适宜的切削参数。值得一提的是，为尽可能减少切削过程的研究成本，借助有限元模拟的方法来形成切削工艺，无疑将可有效优化现有的参数，此方法也由此获得较为广泛的多方位应用。以 Deform3D 仿真软件为基础，将可成功针对 GH4169 高温合金车削构建科学完善的有限元模型。与此同时，还可借助某正交试验方法的作用，针对切削因素相对于切削力而产生的实际影响进行深入研究。并建立切削力经验公式。通过所得研究结果将可得知：GH4169 合金当处于高温切削时，切削深度将会对其表现出的切削力产生尤为显著的影响，进给速度次之，随后才为切削速度。若前两者逐步提高，则切削力也将随之攀升，而若切削速度逐步提高，则切削力将会随之降低。关键词：镍基高温合金 GH4169；Deform 3D 仿真；切削用量三要素，切削力AbstractNickel-based superalloy GH4169 maintains high strength and good stability when exposed to high temperatures. For this reason, it has gained a wide range of practical applications in the aviation and military fields. However, because it has poor hardness during processing and cannot guarantee relatively good electrical conductivity, it is difficult to process. This limits its own multi-faceted application. Therefore, a more in-depth and detailed analysis of the cutting performance of the nickel-based superalloy and the cutting force change during cutting will help to select appropriate and appropriate cutting parameters. It is worth mentioning that in order to minimize the research cost of the cutting process, the finite element simulation method is used to form the cutting process, which will undoubtedly effectively optimize the exi...
