飛機(jī)起落架用超高強(qiáng)度鋼應(yīng)用現(xiàn)狀及展望飛機(jī)起落架用超高強(qiáng)度鋼應(yīng)用現(xiàn)狀及展望Present Status and Prospect of Ultra High Strength Steel Applied to Aircraft Landing Gear 結(jié)合飛機(jī)起落架設(shè)計(jì)思想和需求,介紹國(guó)內(nèi)外飛機(jī)起落架用鋼的應(yīng)用及研究進(jìn)展,總結(jié)起落架用鋼的應(yīng)用特點(diǎn)和思路,對(duì)比國(guó)內(nèi)外飛機(jī)起落架用鋼的差距。目前飛機(jī)起落架用鋼已經(jīng)形成了低合金超高強(qiáng)度鋼和高合金超高強(qiáng)度鋼并用的材料體系,建立了完整的抗疲勞制造技術(shù)體系。我國(guó)起落架用超高強(qiáng)度鋼的研制和應(yīng)用處于國(guó)際先進(jìn)水平。分析討論了飛機(jī)起落架用超高強(qiáng)度鋼的發(fā)展方向。 The paper presents the domestic and overseas current status of the steel applied to aircraft landing gear in combination of the design concept and requirements for aircraft landing gear. The application features and concept of the steel used for landing gear are summarized and the domestic and overseas status are compared. For the moment, the low-alloy ultra-high strength steel and high-alloy ultra-high strength steel are all being used in the material system for aircraft landing gear steel, and the complete technical system for its anti-fatigue manufacturing is built. At present, China's development and application of high strength steel applied to aircraft landing gear is at the world advanced level. At last, the prospect for future development is analyzed. 全文下載:https://pan.baidu.com/s/1nvA9Qqt
