This paper describes the structural optimization technique with FEM topography optimization technology, the design shape of engine components have been optimized based on the sensitivity analysis, and the purpose is to minimize the vibration of engine block. The process of structural optimization display that the vibration on FEM models of engine block as boundary conditions for subsequent topography optimization were used to be an output from dynamic response analysis, and the loads exerted on the FEM models are acquired from the multibody dynamics system, and topography optimization is performed to detect the effective design parameters of engine block shape to structural strength, to reduce the vibration velocity intensity. This paper presents today’s computer design capabilities in the simulation of the dynamic and vibration behaviour of engine and focuses on the relative merits of modification and full-scale structural optimization of engine, together with the creation of new low-vibration designs. The results verify the analysis, assessment and vibration optimization of the engine.
