How do I model a lubricated contact in a simulation setting?

What is the correct combination of numerical methods for different regimes of lubrication?

How do I consider realistic system level data as well as experimental inputs to achieve practical results?

Learn how to realistically and practically simulate lubricated contacts with this e-learning course from NAFEMS.

Simulation of Lubricated Contacts

Low Load Hydrodynamic and High Load Elasto-Hydrodynamic Modelling From Contact to System Levels

This course is designed to develop skills and knowledge in simulating lubricated contacts using numerical methods. Lubricated contacts form a lubricant film which completely or partially separates contacting surfaces.

This film of lubricant generates viscous friction, usually the largest contributor to the frictional losses. The pressure generated in the film is also different from dry contacts. Hence, this simulation affects any durability and surface fatigue analysis. The dissipated energy generates heat, leading to thermal behaviour of the contact which will also be discussed in this course.

Finally, as any numerical method, the computational tribology requires system considerations as well as experimental inputs to deliver realistic data. These two aspects will be covered appropriately in this course to ensure practicality of the developed knowledge.

By the end of this course, you will have developed a unique capability in simulating and predicting lubricated contacts.

Who should attend?

Engineers dealing with systems which contain lubricated contacts, such as those with gears, bearings, seals, guideways and sliders.

Engineers who design above systems for desired durability, friction and dynamic refinement

What will you learn?

Ascertaining regimes of lubrication for a simulation case
Calculating, pressure distribution, film thickness distribution, temperature distribution and friction in lubricated contacts.
System level considerations, including how a lubricated contact behaves under dynamic loading and within a structure.
Making a connection between the simulation and experiment on the same system.
Taking into account oil availability in the system (starvation).

Why an e-learning class?

Travel and training budgets are always tight! The e-Learning course has been developed to help you meet your training needs.

Engineering Board PDH Credits

*It is your individual responsibility to check whether these e-learning courses satisfy the criteria set-out by your state engineering board. NAFEMS does not guarantee that your individual board will accept these courses for PDH credit, but we believe that the courses comply with regulations in most US states (except Florida, North Carolina, Louisiana, and New York, where providors are required to be pre-approved)

Special Note(s):

Telephony surcharges may apply for attendees who are located outside of North America, South America and Europe. These surcharges are related to individuals who join the audio portion of the web-meeting by calling in to the provided toll/toll-free teleconferencing lines. We have made a VoIP option available so anyone attending the class can join using a headset (headphones) connected to the computer. There is no associated surcharge to utilize the VoIP option, and is actually encouraged to ensure NAFEMS is able to keep the e-Learning course fees as low as possible. Please send an email to the e-Learning coordinator (e-learning @ nafems.org ) to determine if these surcharges may apply to your specific case.

Just as with a live face-to-face training course, each registration only covers one person. If you plan to register a large group (10+), please send an email to e-learning @ nafems.org in advance for group discounts.
