As we are moving towards complete electrification from combustion engine to electric motor, the system design approach also changes due to application.

For a range of kg EV powertrain weight, number of mounts as well as mount locations, orientations and stiffnesses plays a significant role during system design. The electric powertrains are usually lighter and their mounts are usually stiffer than the mounts for typical combustion engines, the static displacements at dead load are usually lower.
That is actually something we observe in some benchmarks - that modified pendulum systems are used mainly for e-motors, which share a common vehicle platform with combustions engines, but if a vehicle is developed exclusively for electric drive, then the mounting system is a three or four point system with bush type mounts in most cases. The methodology of decoupling and separating the powertrain rigid body modes is the same.https://cornadesjou.gq

However, the targets for modal alignment should be adjusted, as idle isolation is not required anymore, because there is no idle excitation with electric powertrains. It will also benefit graduate engineering students with a strong interest in electric machines and drives. KGaA - Betreiber - www. All rights reserved.
