FEM of Speed Effect Compensation for Hydrodynamic Journal Bearing in Continuous Hot Strip Mill
-
摘要: 采用有限元方法求解雷諾方程,對油膜厚度進行計算機數值模擬,以評價不同軋制工況下油膜軸承的承載能力與特性參數.計算得出的不同軋速與軋制壓力下膜厚預報值及權厚控制曲線,與實際數據吻合.Abstract: The finite element method (FEM) is used to solve the Reynlds equaion and to perform the computer numerical simulation for the calculation of oil film thickness and the evaluation of the parameters and loading capacity of the oil film bearing considered under different rolling conditions. The forecasted film thickness from the computation and the gauge control graph are close co-related to the practical status.
