Highly Optimized Passive Lubrication System for an EV Transmission

A welcome address to Altair's ATCx CFD virtual event hosted in 2020, presented by Andy Fine, VP CFD Solutions EMEA at Altair.

CFD for Oiling and Thermal Management of Drivetrain Components, presented by Dr. Miloš Stanić, Product Manager at Altair during the ATCx CFD 2020.

Recorded at the ATCx CFD 2020 virtual event, this is a Q&A with Torbjörn Larsson, Former Head of CFD for Ferrari F1. With previous roles at BMW F1, General Motors and Saab Military Aircraft, Torbjörn has 30 years of industrial experience in fluid mechanics and CFD. Listen to the questions our audience posed to Torbjörn in this 30 minute session.

Learn how Altair’s flexible and efficient CFD solvers pave the way for simulation-based design in the field of Computational Fluid Dynamics.

This presentation focuses on presenting a synergy of different simulation methods and tools towards the accurate prediction of power losses, oil distribution and thermal effects focusing on an automotive and aerospace gearbox example. A number of different approaches are described, including CFD, gear design, bearing design and selection and oil selection, with the aim of maximizing efficiency and ensuring adequate lubrication of critical components and cooling of the powertrain components (e-motor and the associated gearbox)

We are right at the beginning of the new mobility era with deep impact on the architecture of cars. Hybridization and electrification are the dominating topics in the automobile industry and consequently the powertrain of cars comes into the focus. However, the development of smart and efficient drive assemblies is challenging due to different and increasing demands such as legal restrictions. Numerical simulations can provide profitable support in the development of such components, especially when they are adopted during the early stages of the design process.
