Innovative lightweight design is the key to reducing consumption and pollutant emissions. Especially the paradigm shift currently underway towards more electrification demands new possibilities for saving weight to be explored. Thus the aim of this webinar is to show how a fatigue life analysis can be carried out for a modern electric drive system. Since vibration phenomena play an essential role here, a modal fatigue analysis is carried out. We present all the necessary steps to set up the modal fatigue analysis in FEMFAT channelmax and the fatigue results. The e-drive system will be subjected to an engine run-up simulation. The add-on tool HARMONIC is used for the data preparation.
