Mechanical tension calculation methodology for the mining transport machine diesel engine cylinder cover fire bottom
Destruction of cylinder covers of diesel engines of mine suspension locomotives or ground mining transport is accompanied by the formation of through cracks in the fire bottom. For the development of measures aimed to increase in reliability of details of the cylinder-piston group of diesel engines of mining transport machines, it is necessary to calculate the mechanical tension in the fire bottom of the cylinder cover. Mining transport machine diesel engine cylinder cover represents irregular shape the fire bottom of which can be represented as a circular plate having four round holes (in some cases two). Influence of pressure on the fire bottom of a mining transport machine diesel cylinder cover can be compared to the influence of the distributed loads on round plates. In the article the calculation technique of mechanical tension in the mining transport machine diesel engine cylinder cover fire bottom is considered. For studying of the phenomenon of the occurrence of mechanical stresses in the details of the diesel engine of mining machines due to their heating, it is advisable to use the finite-difference scheme of the ANSYS program complex.
