| Abstract: | In this paper, the deformation and stress field of a oil-cooled thin wall SG cast iron piston from a newly-designed marine diesel engine have been calculated by using 3D finite element method. The fatigue strength and thermal deformation have been then evaluated and checked. The characteristics of the deformation and stress field on these pistons have been analysed. Some valuable key points for piston design are presented. |
