The evaluation of the stress-strain state for the cylinder heads of high-powered diesel engines using the multiphysics ANSYS technology

摘要

The researchers have built a calculation model for comparative assessments of the heat balance, heat and stress-strain state for the head and cylinder liner of forced diesel engine, which model takes into account the redistribution of the quenching fluid between the cylinder head and crankcase. Computational experiments have been performed. The trade-off approach to the design of a diesel engine cooling system has been demonstrated to find out that improved cooling of the cylinder head is accompanied by deteriorating thermal state of the crankcase and the cylinder liner.
