某发动机催化器支架FEA分析

FEA Analysis on Catalyst Bracket of an Engine

采用ABAQUS软件对某发动机的催化器支架进行了FEA分析,计算其主要阶次的固有频率、支架的应力分布云图,最后对支架的高周疲劳进行了分析,结果显示满足评价指标,表明该支架结构设计合理,能够满足使用要求。

FEA analysis on catalyst bracket of a certain engine is carried out using ABAQUS. The nature frequencies,stress contours of this bracket are calculated. At last a high cycle fatigue is evaluated based on the stress results. The results can meet the evaluation standard, and indicate that the design of bracket is rational and can meet the use requirements.
