The high-frequency noise that tends to occur in electric axles is generated by electromagnetic forces from the motor, gear and bearing forces from the transmission and the DC/AC converter.</p><p><br/></p><p>For the transmission, the simulation of the NVH behavior - noise, vibration and harshness - is the basis for optimizing the gear teeth. For this purpose, the vibrations forced in the drive train by the excitation in the gearing are calculated with&nbsp;KISSsoft, which determines the variable forces and moments at the bearings. These values are then transferred to the multi-body simulation program&nbsp;RecurDyn&nbsp;as excitation for the housing. The radiated power is determined for the housing, thus enabling an evaluation of the noise behavior of the gear unit. This calculation is now offered as a service of&nbsp;KISSsoft.</p><p><br/></p><p>If you would like to learn more on this subject, please register for the free web demo below on December 8, 2020, in which&nbsp;KISSsoft&nbsp;will present the NVH calculation process with the software packages&nbsp;KISSsoft&nbsp;and&nbsp;RecurDyn.</p><p><br/></p>
