摘要
建立了S195柴油机气缸套的三维有限元模型,利用ANSYS有限元分析软件的APDL语言工具加载了边界条件,分析了标定工况下气缸套温度场及热变形,计算结果与实测值吻合,精度比传统方法有所提高,从而证明这种加载边界条件方法的可行性.计算结果表明:在标定工况下气缸套的工作温度最高达483.05 K,位置在缸套内壁面的上部区域,缸套内壁径向的最大变形量为0.209 mm,位置在缸套上部.
3 -D FEM for the cylinder liner of S195 diesel engine was build up. After applying APDL of ANSYS software to load boundary condition, the temperature field and the thermal deformation under the condition of engine standard power were analyzed. The calculating results were much the same with the testing results and they were more accurate than the results calculated in the traditional way. It was verified that the method of loading boundary condition was feasible. The research indicates： under the standard power condition, the working temperature of cylinder liner, which appears on the upper part of the cylinder liner＇s inner surface, could be high up to 483.05 K. The most radial deformation of cylinder liner＇s inner wall, which appears on the upper part of cylinder liner, was 0. 209 mm.
