Next Steps with Multibody Dynamics Simulation

This 3-session course offers guidance on how to assess and plan the task of carrying out advanced Multibody Simulation Analysis of systems and mechanisms. By attending, you will build a theoretical, numerical and methodological background which will allow you to build advanced MBD models.

Examples are discussed in detail to illustrate the different technologies. Focus is put on how to introduce more realism in an MBS model so to better replicate the physics, ending up with latest trends in the discipline, and special focus on the observed convergence between MBD and Finite Element Analysis, including:

Engineering assessment – is your model realistic?
Going through advanced concepts like gear models, tires, contact
Specific MBD packages and verticals
Introducing more realism through the use of nonlinear flexible bodies
Optimizing a model
Simulating Multiphysics, …
Link with PLM

What will you learn?

Attendees will explore:

How to build advanced MBS models using commercial codes
How to manage tricky aspects of complex model building
How to include more realism in my MBD models
How MBS and FEA are converging so to better simulate nonlinear effects
How to model Multiphysics, how to optimize an MBD model

Who should attend?

Designers, Engineers interested in MBS and looking to build models better representing the physics
Engineers familiars with numerical simulation but not MBS and interested in moving to this area
Designers of systems, interested in using MBD for the simulation of complex systems and subsystems
Engineers familiar with MBS but interested in new trends like use of nonlinear flexible bodies, links with PLM, …

Strong effort is made for the course to be MBD software neutral. However, examples from some of the more well-known and popular software may be used throughout the sessions.

The course is completely code independent.

Course Process and Details

This is a 3-session online training course, with each session lasting approximately 2 hours, depending on homework submissions, questions & discussions.

You can attend the sessions live, and/or stream on demand. For additional info on telephony charges please email e-learning @ nafems.org .

A full set of notes in PDF format will be available for download.

Personal passwords are provided to allow you to access e-learning backup material via our discussion forum. Reading lists, homework submissions and supplementary information are all available via the discussion forum.

To get the most out of the course, participation in forum discussions is very much encouraged. Typically the forum remains open for 4 weeks after the last live session, giving you plenty of time to catch up with homework, review and ask questions.

Note: homework is purely voluntary
