【Abstract】 The method for solution lubrication performance was described by the PDE toolbox and window functions in MATLAB. Firstly, lubrication problems were transformed into standard functions of MATLAB, and then static characteristics of oil film such as pressure and pressure gradient were obtained by finite element with triangle-shaped grids and a few programs. The experience shows that MATLAB is convenient and highly efficient tool for numerically solving and visualization of lubrication question.更多还原
