Research on a Diesel Engine Cylinder Block Based on Structural Optimization Method
Cylinder block is the largest part of the mass of the engine largely affects the weight of the engine,so it is particularly important to reduce its weight.In this paper,a two-stage optimization method,which combines the flapping optimization method and the shape optimization method,is proposed to optimize the cylinder block The most reasonable reinforcement shape is sought by shape optimization.Finally,the maximum stress of cylinder block is reduced by 10.6%and the weight of cylinder block is reduced by 3%.At the same time,this research can also provide some theoretical ba-sis for the structural optimization and lightweight of other engine components.
