准确地预估产品的疲劳寿命对于电动汽车关键零部件的结构强度设计以及可靠性设计具有重要作用。以实测强化路道路的载荷谱为出发点,提出了实测载荷谱数据处理与分析的方法,基于Miner准则,得出了车辆在空载、半载以及满载下的载荷数据,通过时域频域处理、损伤等效处理等,得到了可供振动仿真分析以及室内台架试验的关键数据;设计开发了一款平行轴式电驱动桥,针对桥壳等关键部件开展了静力学分析和模态分析,得出了桥壳不会因为路面激励而产生扭转和弯曲现象的结论;基于nCode DesignLife仿真分析软件得出了桥壳疲劳寿命与损伤值分布,通过桥壳耐久试验验证了仿真分析的准确性;基于实测的强化路道路载荷谱,在整车振动试验台上开展了15 000 km的强化路室内整车振动试验。试验表明,该电驱动桥产品整体寿命及可靠性满足设计要求,同时验证了分析方法的可靠性。
Accurately predicting the fatigue life of products plays an important role in the structural strength design and reliability design of key components of electric vehicles.Starting from the measured road load spectrum of the reinforced road
a method for data processing and analysis of measured load spectrum was proposed
based on the Miner criterion
the load data of the vehicle under no-load
half-load and full load were obtained
and the key data for vibration simulation analysis and indoor bench test were obtained through time-domain frequency domain processing and damage equivalent treatment.A parallel-shaft electric drive axle was designed and developed
the statics analysis and modal analysis were carried out for key components such as the bridge shell
and the results concluded that the bridge shell would not have torsion and bending caused by road surface excitation.Based on nCode DesignLife simulation analysis software
the fatigue life and damage value distribution of the bridge shell were obtained
and the accuracy of the simulation analysis was verified by the bridge shell durability test.Based on the measured road load spectrum of the reinforced road
a 15 000 km vehicle vibration test was carried out on the vehicle vibration test bench for the electric drive axle.The test shows that the overall life and reliability of the electric drive axle meet the design requirements
and the reliability of the analysis method is verified.
