A comprehensive survey of the analytical, numerical and experimental methodologies for dynamics of multibody mechanical systems with clearance or imperfect joints

The reach of tribology has expanded in diverse fields and tribology related research activities have seen immense growth during the last decade. This review takes stock of the recent advances in research pertaining to different aspects of tribology within the last 2 to 3 years. Different aspects of tribology that have been reviewed including lubrication, wear and surface engineering, biotribology, high temperature tribology, and computational tribology. This review attempts to highlight recent research and also presents future outlook pertaining to these aspects. It may however be noted that there are limitations of this review. One of the most important of these is that tribology being a highly multidisciplinary field, the research results are widely spread across various disciplines and there can be omissions because of this. Secondly, the topics dealt with in the field of tribology include only some of the salient topics (such as lubrication, wear, surface engineering, biotribology, high temperature tribology, and computational tribology) but there are many more aspects of tribology that have not been covered in this review. Despite these limitations it is hoped that such a review will bring the most recent salient research in focus and will be beneficial for the growing community of tribology researchers.

There is the direct interaction between the crankshaft and the crankshaft bearing in an internal combustion engine Current lubrication analysis of the crankshaft bearing was generally limited in the tribology discipline, only the factors relating to the bearing were considered, and the journal axis was generally supposed to be parallel to the centerline of bearing In reality, the crankshaft deformation under load will result in the journal misalignment in the bearing Although the journal misalignment was considered in a few of the lubrication analyses of crankshaft bearings, the causes of journal misalignment were usually thought to be caused by the manufacture, the assembly errors and the deformation of cylinder block In order to simplify the problem, the journal misalignment was generally assumed to have constant magnitude and direction in an operating cycle of engine In this paper, a crankshaft-bearing system was taken as the research object and the lubrication performance of crankshaft bearing considering the crankshaft deformation under load were analyzed The crankshaft deformation and the bearing load were calculated by the whole crankshaft beam-element method The deformation of bearing under oil film pressure was calculated by the deformation matrix method The axis orbit of the crankshaft bearing was calculated by the dynamic method The results show that the local axis orbits on the front-end and the rear-end plane of crankshaft bearing are changed remarkably when the effect of crankshaft deformation is considered The journal misalignment results in the maximum oil film pressure of bearing be increased obviously, the minimum oil film thickness of bearing be reduced in the most of time of an engine cycle and the oil film pressure distribution of bearing be changed, but has only a little effect on the end leakage flow-rate and the frictional coefficient of bearing © 2011 SAE International
