Understand and Simulate Damping of Mechanical Vibrations

Damping as an annoying unknown or for the targeted reduction of vibrations?


Training eLearning Expert

Learn how to selectively reduce undesirable vibrations in simulations and take parasitic damping into account. This training is offered as a 2-day course or alternatively as a self-paced eLearning course.

2 days

Basic knowledge of Ansys Mechanical

Software used
Ansys Mechanical

  • Material and component damping in accordance with the VDI 3830 classification
  • Practical exercises for these damping phenomena in Ansys Mechanical
  • Methodical procedure for reducing vibration through simulation
  • Consider parasitic damping effects such as joints


Damping is frequently used in technology to reduce vibrations. On the other hand, it is essential for the accuracy of a structural dynamics simulation to know and be able to adequately model parasitic damping mechanisms such as joint damping and radiation damping through adjacent fluids.

You would like to not only measure the vibration problems in your products, but also analyze them in a targeted manner and develop countermeasures? You already solve engineering problems related to structural dynamics and would like to systematically explore the topic of damping in theory and practice? This course is for participants who have previous knowledge in dealing with dynamics simulation but have questions about handling different damping models skillfully.

In this training, you will learn about the most important damping effects based on the agenda of the VDI 3830 for material and component damping. You will learn how these damping phenomena can be mapped in Ansys Mechanical in selected practical exercises. Learn the methodical procedure to successfully carry out typical vibration reduction tasks using simulation.

Damping, Isolating, Absorbing - with the eLearning course ‘Understand and simulate damping of mechanical vibrations’, I feel well equipped for modeling and selecting suitable simulation methods for vibration reduction. As an extension to the training ‘Structural dynamics and vibration technology’, I can highly recommend this training.

Do you have questions on the training or the eLearning?

When will I receive the final confirmation for my training booking?

Straight after you sign up, an automatic confirmation of receipt will be sent to the email addresses you provided. Once you have successfully verified the data you provided, you will receive your personalized sign-up confirmation, containing further information on course fees, the billing address, etc., by email within two to three working days.  

As soon as the minimum number of attendees has been reached, you will receive a final training confirmation containing further information. If you have booked an on-site training, we recommend that you wait until you have received this final confirmation before booking your travel and accommodation.

If the minimum number of attendees is not reached, we reserve the right to cancel the training seven days before it is due to start at the latest. We are happy to inform you on changing your booking to an alternative date. Please note that we accept no liability for hotel or travel bookings that attendees have already made.

When is the sign-up deadline for a training?

Training places will generally be allocated based on the order in which attendees sign up. For this reason, we always recommend booking for your desired date as early as possible.

As long as a coures still has free places, it can be booked.

At what time do the training courses begin and end?

Usually the training courses start at 9:00 am and end at 5:00 pm of the respective local time. The actual course times will be stated in the booking confirmation. Please note that, depending on the training host, there may be a possible time shift between your and the provider's local time. Therefore all local times are provided with the valid time shift to Greenwich Mean Time (GMT). 

Can I test the eLearning offer without obligation?

To get a clear impression of our online learning format, we offer you a trial allowing you access to the starting module of an eLearning course of your choice. No costs, no cancellation period or anything similar. Moreover, with this free test access you can check all the technical requirements for a smooth learning process. You can easily request the free module from any eLearning course.

How much time should I allow for an eLearning course?

Each online course day comprises four eLearning modules. You should ideally allow 90 to 120 minutes of uninterrupted learning time for each module. This will allow you to acquire the knowledge provided by a module and to consolidate it through quiz questions and Ansys exercises. By dividing each module into micro learning units, you can also make good use of smaller time windows, such as on your commute.

For how long can I access the learning content?

Prerequisite for the use of the eLearning courses is the use of a personalized access to the CADFEM learning platform. When purchasing an eLearning course, access to the learning platform is 365 days. As a subscription user, access to the learning platform starts and ends with the start and end of the flat rate. With the start of a further learning product (Learning Subscription, training, eLearning), access to your content is extended by 365 days.
