Research on optical flat models of stresses in the crankpin of internal combustion engine

The intensity of the contour strains of the oil channel is determined by the method of photomechanics in the consequence of the loads of the crankpin in the working cycle of the internal combustion engine. The studies have made it possible to establish the qualitative and quantitative composition of the stresses on the hole contour of the oil channel against deformation of the bending and torsion of its connecting rod. © The Authors, published by EDP Sciences, 2018.
