摘要
利用有限元方法,基于sehitoglu低周疲劳损伤模型,针对稳态温度场和瞬态温度场两种工况对某发动机缸盖进行低周疲劳分析对比。分析结果表明,瞬态温度场工况下的缸盖低周疲劳寿命远低于稳态温度场工况下的疲劳寿命。
Used the finite element method, based on the model of sehitoglu low cycle fatigue, the cylinder head low cycle fatigue analysis has been performed by consider the steady state temperature field and transient state temperature field. The result shows the low cycle fatigue life of steady state is higher than the transient state＇s.
