背景
In commercial aviation, landing struts are critical components that endure substantial stress upon landing. The high-performance demands placed on these struts require advanced manufacturing techniques to ensure their durability and reliability. A leading commercial aircraft manufacturer needed a solution to enhance the structural integrity and lifespan of their landing struts. Inertia welding technology was identified as a suitable method for creating robust and dependable joints within these critical components.
挑战
商用飞机的着陆支柱必须承受高负荷和重复应力。传统的焊接方法有时会导致接头薄弱，从而影响支柱的整体安全性和耐用性。飞机制造商需要一种解决方案，既能生产出高强度、抗疲劳的焊缝，又不会增加重量或改变部件的整体几何形状。焊缝还需要满足严格的航空航天安全和质量标准。
解决方案
Inertia welding, a process that joins materials by rotating one piece at high speed and pressing it against a stationary piece, was selected for its ability to create strong, high-integrity joints with minimal heat-affected zones. This process is particularly suitable for cylindrical parts like landing strut rods, which benefit from the even distribution of heat and pressure.
制造商使用惰性焊条连接着陆支柱内的高强度合金部分。这种方法可以精确控制焊接过程，从而产生始终如一的坚固接头。使用惰性焊接的好处包括：
- 增强接头强度：惯性焊接过程中产生的摩擦热形成具有高抗拉强度的固态结合，确保接头不易疲劳和磨损。
- 减少缺陷：由于惯性焊接的热影响区最小，因此可以降低出现裂纹或其他缺陷的可能性，从而降低结构完整性。
- 提高生产效率：与传统焊接方法相比，惯性焊接是一种快速工艺，可缩短生产周期。
结果
着陆支柱使用惯性焊条，使接头具有出色的耐久性和抗应力断裂性。测试表明，在循环负载条件下，支柱的性能有显著改善，这是衡量其在商用航空中的使用寿命和可靠性的关键指标。此外，惯性焊接支柱通过了所有安全认证，证实其符合严格的航空航天标准。
结果
The aircraft manufacturer achieved enhanced safety and reliability for its landing struts, contributing to improved aircraft performance and reduced maintenance costs. The success of this project demonstrated the value of 惯性摩擦焊 in critical aerospace applications, paving the way for its broader adoption in commercial aircraft manufacturing.
