• 論文の詳細を見る

• A numerical procedure for non-steady 3-dimensional elastohydrodynamic lubrication analysis was applied on the cam-roller contact of the valve mechanism for a marine diesel engine. Both the pressure distribution and the film thickness between the cam and roller follower acting dynamic load were calculated for each time-step of the whole rotation cycle. A new profiling method for roller edge was suggested using the results of elastohydrodynamic lubrication analysis. The analysis results of the new profile roller were compared with those of the conventional dub-off profile roller. The peak pressure at the roller edge was removed completely with the new profile.
