Challenge
These developments also have an impact on the elastomer components and systems used in the vehicle, e.g. on the engine mountings. This has to be adapted in detail to the drive technology used in each case and has a decisive influence on driving comfort, i.e. the oscillations, vibrations and acoustic phenomena perceivable in the vehicle.
While current combustion engines are excited in particular by low-frequency gas and mass forces, electric drives tend to produce high-frequency excitations up to the kHz range. Since the "masking combustion noises" are missing here during driving, these high-frequency disturbances can be subjectively perceived as particularly unpleasant.
