🎓Development of simulation methods for predicting and influencing the NVH behaviour of e-bike drive units

The operation of an e-bike generates vibrations and noise, e.g. due to the functioning of the drive unit or the interaction between the rider and the bike. Dynamic effects cause excitation along individual structures up to the system level. Sound is also emitted into the environment from free surfaces. As the development of e-bikes is currently being strongly promoted and noise/vibration issues need to be better understood, a computer-aided model of the drive unit is being developed as part of KEVIN STEINBACH's doctoral thesis. The simulation model will then be used to map and predict the NVH behaviour (noise, vibration, harshness) of the drive unit. This would enable optimisation measures to be carried out on virtual prototypes and – in the interests of resource-efficient development – reduce time-consuming test samples.
