摘　　要：建立了CA6102型发动机机体有限元力学计算模型。确定了计算中的位移边界条件,并对静态和实际工况下的机体的应力和变形进行了计算。结果表明,该机体所受应力较小,且分布均匀;机体的变形主要是横向和纵向的弯曲变形,且最大变形发生在机体的中部,对主轴承工作有较大的影响。A mechanical model for finite element calculations of CA6102 engine c(?)linder block is set, up, the displacement boundary condition needed in calculations is determined, then the stress and strain of cylinder block under static and actual operating conditions are calculated. The calculated result(?) show that the stress in the cylinder block is smol1 and evenly distributed, deformation in the block is mainly transverse and longitudinal bending de(?)crmation and maximun deformation occurs at middle of block, which has an obvious effect on the working condition of main bearings.
