摘　　要：针对150型柴油机热负荷问题,以实测温度场数据为基础,确定了气缸套的换热边界条件,建立了完整的气缸套温度场计算模型。运用有限元法分析了150型柴油机标定工况下气缸套三维温度场及热变形。分析结果表明:最高温度为209℃,位于气缸套内壁上端;最大径向变形量为0.244 mm,位于气缸套上端。To aim the heat load problem of 150 diesel engine cylinder liner,based on the temperature field measured,the boundary condition of cylinder liner was determined,a comparatively perfect mathematic mode and a geometric model are built up,and the analysis of the cylinder liner's three dimention temperature field and the thermal deformation was performed with FEA method.The result shows that the highest temperature of cylinder liner is 209℃,which appears on the upper part of the cylinder liner's inner surface.The peak radial deformation is 0.244 mm,which appears on the upper part of cylinder liner.
