作为增压器核心零部件,涡轮箱的疲劳失效主要由热载荷引起。结合汽车发动机可靠性试验方法规范,通过CFD、FEA仿真和FEMFAT疲劳,计算分析增压器在不同工况下的温度及累积塑性应变分布情况和涡轮箱危险部位的疲劳损伤,对涡轮箱的疲劳寿命进行预测分析,经过计算分析该涡轮箱疲劳寿命约为1490 h,能够满足实际使用要求。

As the core components of the supercharger,the fatigue failure of the turbine box is mainly caused by the thermal load.Based on the CFD,FEA simulation and FEMFAT fatigue calculation,this paper analyzes the temperature and cumulative plastic strain distribution of the supercharger under different working conditions and the fatigue damage of the dangerous parts of the turbine box.The fatigue life of the turbine box is analyzed.The fatigue life of the turb...
