To investigate the mechanism of water-cooled valve seat sealing failure on the high-temperature exhaust side of the cylinder head of marine diesel engines due to progressive thermal deformation during long-term service, a finite element simulation method incorporating temperature history effects was proposed, based on a thermal viscoplastic constitutive model. The Chaboche nonlinear combined hardening equations and the Norton-Bailey creep equations were utilized to describe the nonlinear deformation induced by thermal fatigue and creep, respectively, and investigate their coupling mechanism. On the basis, introducing the load attenuation to analyze the impact of creep fatigue loading on structural stiffness degradation, thereby elucidating the evolution of valve seat sealing performance. Research findings reveal that the average error in deformation of cylinder head valve seat holes is approximately 16%, with a 19% improvement in calculation accuracy compared to existing methods. Moreover, the maximum attenuation of the sealing load for the valve seat hole reaches 75%, resulting in sealing failure and water leakage. Progressive deformation is primarily controlled by plastic strain during the heating and cooling stages of the thermal cycle, with influence from the creep-enhanced plastic deformation mechanism during the high-temperature holding stage. This underscores that progressive plastic deformation over long-term service periods is the fundamental cause of valve seat sealing failure.

为了探索船用柴油机缸盖在长期服役下因渐进变形而导致的高温排气侧水冷阀座密封失效机理,提出了考虑温度历史效应的缸盖热黏塑性有限元仿真方法.该方法采用Chaboche非线性混合硬化方程和Norton-Bailey蠕变方程,分别描述了热疲劳和蠕变产生的非线性变形,并研究了二者的耦合机制.在此基础上,引入载荷衰减度分析了蠕变疲劳加载对结构刚度退化的影响,并解释了阀座密封性能的演变.结果表明:缸盖阀座孔变形的平均误差约为16%,计算精度比现有方法提高了19%;此外,阀座孔密封载荷衰减度最大达到75%,导致密封失效,引起漏水;渐进变形主要受热循环中升温和降温阶段的塑性应变控制,并受到高温保持阶段蠕变增强塑性变形机制的影响,长期服役下渐进的塑性变形是导致阀座密封失效的根本原因.
