Research on Fast Direct Algorithm for Point Contact Elastohydrodynamic Lubrication

Based on the fast and direct algorithm of point contact elastohydrodynamic lubrication(EHL),a new algorithm of block by column and solution by column for solving point contact EHL was proposed to further reduce the calculation amount and improve the calculation efficiency.The accuracy and efficiency of the new algorithm were verified,and the applicable range of parameters of the new algorithm was discussed.The results show that the new algorithm has a higher calculation accuracy and efficiency,and has a wider range of parameters,which can get good convergence solution under light load,medium load and heavy load.The new algorithm is a further improvement and development of the point contact EHL algorithm.
