摘要
利用现代CAD技术,建立了6114柴油机缸盖的实体模型和有限元模型,并对有限元模型进行了离散误差的收敛性分析。在此基础上,进行了缸盖的温度场、预紧工况机械应力、爆发—热耦合应力的计算分析。确定了各影响因素在缸盖上造成应力集中的主要位置,为结构改进提供参考。
The solid model and finite element models of cylinder head are given by means of the advanced CAD techniques, and convergence analysis of discrete errors of finite element model was also conducted. Further more, of this temperature and stress fields of cylinder head under different working conditions were simulated. The calculated results is helpful to find the places where failures might happen, and provide the information for improving cylinder head structure.
