Vibrations and Acoustics 2022-2023

Link to material to watch before the class for the vibration part

News

  • For the session on Wednesday Dec 7, please watch the video related to vibration isolation. In addition to a wooclap session on vibration isolation, we will be discussing the first three case studies for the oral exam for which vibration isolation is one of the relevant remedial measures. Note that this will be an interactive class discussion and that there is no support/slides detailing the case studies, so it is strongly advised to be present in class and take notes.
  • For the session on Wednesday Dec 14, there is no video to watch and we will go over the last two case studies, as well as any question you may have about the course.
  • For the session, Wednesday 30/11/2022, please watch the following videos : Vibration testing I and Vibration testing II. The slides of the case studies can be found on Canvas
  • For the session 08/11/2022, please watch the videos : ‘remdial measures’, ‘damping’ and ‘tuned vibration absorbers’
  • For the session of 25/10/2022, next Tuesday, we’ll discuss ‘Vibration problems‘ and ‘Dynamic response computation‘ (See video in Dynamics of structures page)
  • For the session of 18/10/2022 we’ll discuss ‘Continuous systems’, ‘Reduction to SDOF systems’ and ‘Flow induced vibrations’.
  • For the third exercise session on 21/10/2022 we’ll continue in Session 2 starting from Exercise 4:  Projecting on the modal space .  I will also shorten session 3 so we can finish everything in a two hour session. 
  • For the session of 11/10/2022 please watch the videos Finite Elements and continuous systems, also review MDOF system video.
  • For the session of 04/10/2022 please watch the videos: SDOF systems (from 28:00), Vibration sources, and MDOF systems. We’ll discuss the content in class during an interactive session.
  • To join the exercise sessions you’ll need to be enrolled in the course ‘Vibrations and Acoustics’ on VUB’s canvas: https://canvas.vub.be/courses/27931. For some of you this will already have happened automatically. For those who haven’t been enrolled you can do so by clicking on the ‘+ Aan deze cursus deelnemen’ button that is visible to you in the top right corner.  You should be able to login with your @vub.be mail address and the password you use for all other tools at VUB. When you are facing troubles with registering on Canvas contact Yacine Bel-Hadj : yacine.bel-hadj@vub.be .“
