Finite Element Analysis and Optimization of S1110 Diesel Engine Body

Abstract:

In order to reduce the mass ratio of S1110 diesel engine, structural intensity and stiffness analysis are performed on the assembly parts of engine body by using the finite element method. Through comparative analysis of more than one calculation scheme, optimization scheme has been got. To ensure the intensity and stiffness of the engine body is not reduced under the premise, optimization scheme makes the body mass greatly reduced from the original engine body’s 38kg to 13.8kg and the engine mass ratio is reduced from 13.2kg/kW to 11.81kg/kW. The results show that, changing the body material from cast iron materials to cast aluminum materials, the body stress distribution trends are similar, but the cast aluminum body deformation increases; increasing the number of cylinder head bolts to 6 can reduce the deformation of the cylinder liner; a reasonable set of stiffeners can reduce the bearing bore deformation.
