摘要
增材制造是先进制造技术的发展方向之一,民用飞机增材制造技术的应用取决于增材制造技术和适航验证技术的成熟度以及材料标准体系的完善度,对民用飞机起落架典型结构所用的A-100、TC18材料进行了激光/电子束增材制造技术应用研究,建立满足适航要求的材料与工艺认证、力学性能表征、内部质量控制与无损检测评价体系。
Additive manufacturing is one of the development directions of advanced manufacturing technology.The application of civil aircraft additive manufacturing technology depends on the maturity of additive manufacturing technology,airworthiness verification technology and the perfection of material standard system.In this paper,A-100 and TC18 materials used in the typical structure of landing gear of civil aircraft are studied in the application of laser/electron beam additive manufacturing technology,and a material and process certification,mechanical property characterization,internal quality control and nondestructive testing evaluation system meeting the airworthiness requirements is established.
