In addition to our forum, we will be carrying out the following workshops. Each attendee will receive a complimentary place on either of these workshops which will both take place on 8th September after the User Forum.



Bearing Workshop

Bearings are used in gear boxes to support the shafts and keep the gears aligned. We will look at bearings in detail to better understand the types of bearings, their nomenclature and basic internal geometry. Once this is understood, you will have a better understanding of the options you have for bearings in your application. Choosing the correct bearing type is not all that must be considered. How it will be installed and what failures can occur will be looked at as well. We will then look at the common bearing capacity standards and life analysis methods associated with some of these standards. To end the workshop, we will use RomaxDESIGNER to apply this knowledge to analyze bearings and examine the results in a gearbox model.



Modern vehicle propulsion systems increasingly use electric motors as the prime mover. The electric motor is typically coupled with a mechanical gearbox to provide desirable torque characteristics for vehicle propulsion and efficiency characteristics for a given drive cycle. The electric motor and gearbox have individual NVH characteristics, but must be considered together to accurately capture the system level NVH performance that can lead to excessive passenger noise and/or poor sound quality. In this workshop, we will review the mechanisms of noise and vibration in electro-mechanical propulsion systems, including motor torque ripple, motor radial forcing functions, rotor imbalance, and gear whine. To start the workshop, NVH theory will be covered for motors and gears. Then, practical examples will be reviewed. To complete the workshop, RomaxDESIGNER simulation tools will be used to apply our knowledge to predict the NVH performance of an electro-mechanical propulsion system.
