The study of the dynamics of the crankshaft mechanism of car engines permits to establish the laws of wear of liners of engines under the influence of different conditions of operation; to improve design features of parts, mechanisms and systems of engines of loading vehicles and machines of cyclic action, which operate mostly in transient conditions.The main purpose of the work is to analyze the conditions and dynamics of the stress state of cylinder liners of a car engine according to the operating conditions, and to identify the changes of the internal diameter of the cylinder liner along the cylinder element.
In order to determine the voltage magnitudes, which appear in the cylinder liners as a result of the influence of intense working conditions and in order to calibrate the experimental setup, the analytical calculations were carried out.
The study of the dynamics of the crankshaft mechanism of car engines helped to ascertain the regularities of wear of cylinder liners of engines under the influence of different working conditions of engine that will permit to continue the improvement of the design features of the parts, mechanisms and systems of engines, which operate in transient conditions. The studies permit to determine the order of magnitudes of deformation and the nature of their origin that allows more reasonable performance of experimental studies.
