基于ABAQUS的发动机排气歧管低周疲劳分析

The Exhaust manifold LCF Analysis Based on ABAQUS

在发动机运转过程中,排气歧管温度会产生周期变化,会导致排气歧管发生低周疲劳破坏,文章基于ABAQUS对某发动机的排气歧管进行低周疲劳分析,研究排气歧管的低周疲劳寿命。

During engine operation, the exhaust manifold temperature will produce periodic changes. This exhaust manifold occurrence o flow cycle fatigue damage. The low cycle fatigue analysis of exhaust manifold out based on software abaqus in this paper. And to search the low cycle fatigue life of the exhaust manifold.
