| Abstract: | Based on the boundary conditions formula obtained by the measured temperature data,the three dimension temperature field of the cylinder liner and the thermal deformation under the thermal analyzing results are given with the FEA method.The result shows that the working temperature of cylinder liner can be high up to 107.3K,and the most radial deformation is 1.8 mm,both of which appears on the upper part of the cylinder liner`s inner surface. |
