초록
The influence of round embossed surface on slider bearing characteristics and its load carryingcapacity is discussed for thin film effect of embossed slider bearing. For the numerical computation of lubricationparameters such as pressure, load capacity and shear stress that are normalized and a Reynolds equation is usedfor the analysis of embossed slider bearing characteristics. For this purpose, the finite difference method of centraldifference scheme is used in this study. In a slider bearing with embossed form, several simulation parameterssuch as pressure, load capacity and shear stress of the bearing can be obtained according to independent parameterssuch as the slope of the slider bearing and number of embossing in the upper slider. Also this results canbe summarized and be stored in sequential data file for latter analysis. After all, their distribution of the pressureand shear stress parameters can be displayed and be analyzed easily by using the developed program with matlabGUI technique. The independent parameters such as a number of embossing and a slope of the embossed surfaceslider are used for discussing simulation parameters of pressure distribution, shear stress and load carrying capacityof the round embossing. These study results reported in this paper should be applied to the other shaped sliderbearing with a rectangular embossed surface or rectangular waved surface.
