摘　　要：以某重型柴油机的薄壁顶置湿式气缸套为研究对象,结合特定热边界条件,对气缸套的稳态温度场进行了有限元分析,气缸套三维温度场的计算结果显示气缸套最高温度为239℃,出现在气缸套活塞上止点附近。通过对比不同气缸套壁厚对壁面温度场的影响,明确了气缸套的变形分析中不同壁厚对气缸套壁面温度的影响,为气缸套结构设计改进提供理论指导和依据。The thin wall wet cylinder liner of a heavy-duty diesel engine was studied in this paper.Combined with specific thermal boundary conditions,the FEM(finite element method) analysis was carried out.The calculation results of three-dimensional temperature field show that the highest cylinder liner temperature is 239℃ near by TDC(top dead center).By analyzing the effect of the different cylinder liner wall thickness on its surface temperature field,the theory instruction and the basis for cylinder liner design improvement were provided.
