Lumped-Mass Dynamic Model [16] The connecting rod in complex motion can be modeled as two lumped point masses, one on the crankpin (in pure rotation) and the other on the wrist pin (in pure translation).

1, both of the value and direction of the load applied to the crankshaft vary with time, so the center of the crankpin has periodic motion relative to the connecting rod bearing center.
Regular repairs of marine diesel engine crankshaft main and crankpin journals surfaces are therefore needed in order to perform partial or complete renovation of the worn crankshaft journals.
To calculate the frictional forces acting on surfaces between the vane and piston, between the piston and crankpin, and of main bearing, Coulomb's friction law is applied.
The cranks are manufactured in the mould, having shape of the cheek with a water-cooled niche in the place of a future crankpin. First billet of the cheek with a crankpin in the form of a boss is melted (Figure 1, a).
They have incorporated the latest generation of highly flexible, accurate, and productive CNC orbital crankpin grinders with CBN abrasives, whereas the use of older style indexing-type crankpin grinders with conventional grinding wheels is still very prevalent in the global diesel engine industry.
For years, most diesel engine crankshaft manufacturers have found crankshaft lines made up of traditional style indexing-type crankpin grinders with conventional grinding wheels to be a cost-effective solution to their manufacturing requirements.
Landis Gardner (Waynesboro, Pa.) has developed its Crank Center grinder that uses a single, narrow CBN wheel to make multiple orbital-grinding passes and a final wiping of each eccentric-diameter crankpin. The single machine does the work of four.
