quenching pre 中文意思是什麼
-
Machining deformation of aircraft monolithic component is simulated by finite element method ( fem ) and validated by experiment. the initial residual stress in pre - stretched plate is generated by simulating quenching and stretching processes. with a single tool - tooth milling process fem, the machining loads in monolithic component material removing is obtained. restart - calculation is put forward to complete the whole simulation of machining process. to verify the fem result, an experiment is carried out. the deformation distribution of the monolithic component resulting from fem shows a good agreement with the experiment result, which indicates that the key technologies presented in the paper are practicable and can be used to simulate the milling process of monolithic component to predict its deformation. lengthy and expensive trial and error experiment process can be avoided
在模擬淬火、拉伸過程獲得含有初始殘余應力的預拉伸板材以及模擬單齒切削過程獲得切削載荷的基礎上，提出並採用接力演算法，對一航空整體結構件的材料銑削過程進行有限元模擬，同時進行了試驗研究.結果表明，有限元模擬的整體結構件的變形與試驗具有一致性，從而證明提出的整體結構件加工模擬關鍵技術的可行性，避免了為研究加工變形而進行的繁瑣的試錯法 -
