摘　　要：建立了YC6108柴油机气缸体的实体模型,并进行了有限元模态分析。重点比较了在不同网格划分精度下,有限元模态分析的结果。研究表明,对于柴油机气缸体这类薄壁铸造的复杂构件,进行有限元模态分析,需要采用很细的网格划分,才能保证较精确的结果。A entity model for the cylinder block of YC6108 diesel engine has been constructed and the modal analysis been implemented.This research focuses on comparing all the modal analysis results with different meshing densities.The comparison indicates that the appropriate results can be obtained only when with fine enough meshing in Finite Element modal analysis,as the cylinder block is a complex and thin cast parts.
