| 總結: | Presents a study on the application of boundary element
method (BEM) to the solution of elastohydrodynamic
lubricated hard rolling contacts in comparison with a
solution using finite difference method (FDM). The
developed program for the solution of Reynolds equation
and the elasticity equation give results of pressure
distribution and the lubricant film thickness for steady
state, isothermal Newtonian lubricant behavior.
Compares the BEM results and the computer effort with
the solution using FDM. Uses an iterative Newton-
Raphson method to solve the non-linearity of the
problem. Discusses the effects of Hertzian pressure and
rolling speeds on film thickness and pressure distribution.
The numerical scheme of BEM has proved to have the
advantage of being very effective and optimum in terms
of accuracy, less computational effort and good constancy
compared to other applied numerical techniques. |
