油膜粘度
英文
oil film viscosity-
Abstract : in this paper, an analytical study of the dynamics of the piston in a reciprocating internal combustion engine is conducted. the equations of reynolds and moving of piston are derived. a useful method of solution is obtained. the method is applied to s1100 diesel engine. the results of this study indicate that piston oil film is found to be sensitive to the piston - cylinder bore clearance, the location of the wrist pin and lubricant viscosity
文摘:對往復式內燃機活塞的動力特性進行了分析研究，導出了活塞潤滑的雷諾方程和活塞運動方程，給出了可供實用的求解方法，並採用這種計算方法對s1100柴油機進行了設計計算與試驗研究.研究結果表明，活塞潤滑油膜歷程與活塞& &缸套的間隙、活塞銷的位置、潤滑油的粘度等因素密切相關The dynamics behaviors of the flexible jeffcott rotor system supported by unsteady short dynamic bearing are investigated. based on nonlinear unsteady - state dynamic n - oil film force model described by three functions the local stability of the periodic solutions with the controlling parameters, rotational speed ratio, imbalance amount, damping ratio and viscidity, are predicted by using the floquet multiplier. it is found that the period doubling bifurcation is caused by a certain imbalance amount and the hopf bifurcation is created by the lost stability of the oil - film
研究了非穩態動載短軸承支撐的jeffcott柔性轉子系統的動力特性，基於可用三個函數表示動態油膜的非穩態非線性油膜力模型，將轉速比、不平衡量、阻尼比、粘度作為控制參數，利用floquet乘子預測周期解的局部穩定性，發現倍周期分叉是由一定量的不平衡引起的，而hopf分叉是由油膜失穩造成的。Taking gear without tooth face invalidation such as agglutination and abrasion as a precondition, and according to the relation between minimal oil film thickness and tooth face roughness of elastic liquid dynamic pressure lubrication theory, viscosity of gear lubrication oil was educed by reliability method in this paper, and the calculation formula has been elicited and applied
