-
摘要: 本文利用剛性微凸體和塑性微凸體的相互作用模型模擬軋制過程中軋輥與軋件的相互作用,根據塑性力學的上界原理,并借助于滑移線原理,優化處理了接觸表面微觀體形的模型,揭示了微凸體幾何形狀以及接觸面連接強度對摩擦系數的影響。Abstract: With the co-operation between the small stiff convexes and small plastic convexes, the co-operation between rolls and rolled piece has been simulated. Combining the up-bound method with the slipping-line method, the model of micro shape on the touching surface has been optimized. The influences of the micro geometry shape of small convexes and the joint strength between convexes on the frition factor are studied.
