Finite Element Analysis of the Cylinder Liner of a 280 Diesel Engine

The Cylinder liner is one of the key components of diesel engine. Combustion chamber set is constituted by Piston, Cylinder head, Cylinder liner and other parts. Its structure and working environment is complex. Received the gas pressure, friction force from high-speed reciprocating motion of the piston and lateral force of the piston, it results in mechanical stress and mechanical deformation. High temperature combustion and high pressure gas make the piston temperature distribution uneven, which results in piston thermal stress and thermal deformation. Therefore, the element analysis of Cylinder liner in the heat load and mechanical load is significant, the finite element analysis shows the deformation and the stress distribution of the Cylinder liner. It is meaningful for improving Cylinder liner design and reliability.
