Addressing a methodology for NVH analysis and simulation of an automotive E-axle.

Attempts to eliminate mechanical drive trains in automobiles and trucks have had limited success because of cost, weight, dynamic characteristic, and efficiency of the alternative components.

The first chapter from a new book by Dr. Hermann J. Stadtfeld provides an overview of the need for new technologies and approaches when it comes to developing transmissions for electric vehicles.

Today is the 50th anniversary of Earth Day. It was fairly big news for me back in 1970 as one of its founders was a U.S. Senator from my home state...

CTI Symposium Presents Latest Automotive Transmission Developments and Applications.

The Past, Present and Future of Vehicle Electrification

Noise issues from gear and motor excitation whine are commonly faced by many within the EV and HEV industry. In this paper the authors present an advanced CAE methodology for troubleshooting and optimizing such NVH phenomenon.

Gear industry experts give their opinions about the most important trends facing gear manufacturers today.

Electrification has already started to have a noticeable impact on the global automotive industry. As a result, the drivetrains of hybrid (HEV) and full electric vehicles (EV) are facing many challenges, like increased requirements for NVH in high speed e-Drives and the need for performance improvements to deal with recuperation requirements. Motivated by the positive validation results of surface densified manual transmission gears which are also applicable for dedicated hybrid transmissions (DHTs) like e-DCTs, GKN engineers have been looking for a more challenging application for PM gears within those areas.

Our industry makes parts for all different types of energy and transportation. AGMA, our national trade association, was formed, in part, because t...
