Finite Element Analysis of Piston in 240 Diesel Engine

Piston set are constitute by the piston,piston pin,piston rings and other parts.The piston is one of the key components of internal combustion engine,its structure and working environment is complex.Received the high gas pressure,high-speed reciprocating inertia force and support reaction force of pin seat cyclical loading,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 piston in the heat load and mechanical load is significant,the finite element analysis show the deformation and the stress distribution of the piston.It is meaningful for improved piston design and reliability.
