NVH
​​​​​​​​​​​​​​

When you close your vehicle door you enter your own acoustic surrounding. Your driving comfort is strongly depending on the sound/noise you hear and the vibrations you feel. Especially in electric driven vehicles the expectation is high to sit in a quiet and comfortable place. This is defined by the vibration behaviour of the powertrain components, the isolation characteristic of the elastic mounts and the dynamic response of the suspension and body.

Developing Comfortable and Reliable Vehicles

We support vehicle development with our NVH simulations and our acoustic software MNOISE already in the early design phase. Finite elements models which can be combined with multi-body system are used to simulate in time domain or directly in the frequency range. Our long-time experience and close co-working with our testing experts allow us to predict acoustics also at the challenging high frequencies of electric drives.

A second focus of our simulation competence is the fatigue assessment of add-on parts like engine components, fuel tanks or inverters including detailed analyses of the electronic board vibration and fatigue of the SMD solder joints.

We are a team of simulation experts with decades of experience in FE and MBS simulations for vehicle development.
