Applying modern design and analysis method

a solid finite element model of piston is presented in this paper. Using this model

the temperature field

resultant stresses and deformation of the piston designed for a new diesel engine have been predicted. The results show that the resultant deformation is not axially symmetrical

too much diametrical deformation on piston contour part is the cause of pulling cylinder

the peak value of resultant stress inside the pin base and on the cooling oil hole is the reason of piston common destroying (the breaking of pin base and cooling oil hole).
