Failure Analysis of Crankshaft by Finite Element Method-A Review Ms.Shweta Ambadas Naik Assistant Prof. Mechanical Engineering Department D.Y.Patil Institute of Engg.and Technology,Pune,India Abstract— The crankshaft is an important and large component of an engine. The function of crankshaft is to converts the reciprocating displacement of the piston into a rotary motion. In this .

Truck Diesel Engine Crankshaft Failure Analysis. ... Each crankshaft was sent for grinding, after a life of approximately 300,000km of service, as requested by the engine manufacturer.

Grinding machines utilized for crankshaft grinding are specially designed to accommodate the complex geometry, particularly, the off-centre pins. Machine manufacturers utilize different strategies to grind the complex shape. In recent years researchers have tried to model the kinematics of the most widely used processes [1,2]. Consequently, they have been able to determine more and less ...

1-10-2003 · Analysis of possible explanations for the problem based on typical crankshaft failure causes; • Definition of laboratory tests to be done. After the analysis of each explanation for the failures was made, and based also on laboratory tests considered necessary, a conclusion has been drawn. 3. Presentation of the problem

Use of worn or improperly dressed grinding wheel when resizing the crankshaft. Journals may result as tapered, hourglass shape or barrel shape Replace/redress grinding wheel Re-grind the crankshaft Localized wear in parts of the bearing surface. Fatigue cracks may occur in these areas. Erosion damaged areas on the overlay due to sharp changes of pressure in the oil film. Vapor cavities ...

The roughing equipment mostly uses a multi-tool lathe to turn the crankshaft main journal and the neck, and the quality stability of the process is poor, and it is easy to generate large internal stress, and it is difficult to achieve a reasonable machining allowance. General finishing uses crankshaft grinding machines such as MQ8260 for rough grinding – semi-finishing – fine grinding ...

Regrinding the crankshaft is an important part of the engine rebuilding process. It was almost an art in the '40s, but it's pretty routine now. However, there are still plenty of myths and misunderstandings that are left over from the past that we still have to deal with today.AdvertisementClick Here to Read MoreAdvertisement One of [.]

The experiment was carried out to verify the analysis, calculation and simulation. 2. Errors Calculation. Errors of CNC crankshaft grinding machine tool are geometrical errors, grinding force errors, thermal deformation errors, servo tracking errors, and so forth. Geometrical errors can be measured and identified, grinding force errors can be calculated, and the other errors are difficult to ...

evaluated the fracture analysis of some crankshafts of four-cylinder diesel engine. FEM results revealed that the most vulnerable point of fracture is on the llet of the last crankpin (closest to the ywheel). Silva [12] examined the failure of the two crankshafts of diesel engines. The grinding operation on the crankshafts were performed after 300000km and after reassembling the crankshafts of ...

Crankshaft grinding is a methodical yet important part of engine remanufacutring. Today, CNC machinery can grinding and polish a crankshaft in a matter of minutes however doing it the manual way provides room for performance upgrades and a keen eye for overall strength of the crank.
