Tutorial on Acoustic Effects confirmed for ASPE conference 2023

This tutorial will aim at providing the attendees with a sound basis for efficiently adressing structural vibrations originating from acoustic pressure fluctuations, namely : airbone vibrations.
While the field of structure-borne-sound is relatively well covered, the converse is not true. One obvious reason is that airborne vibrations can usually be ignored, unless sound pressure level are considerable, or if admissible vibrations amplitudes are very small.
In the first case, typical of aerospace launchers or power generation industry, detailed simulations are conducted and further validated via testing. or, when configurations are similar enough for project-to-project deviations to be remain minimal, they can be handled via design-by-rule procedures. For particularly demanding precision engineering tasks however, the allowable levels can be extremely small, while geometries and mechanical configurations are be highly diverse, ranging from slender (vibration immune) supports to large (vibration prone) enclosures .
Overall, for the precision engineer, there is a need for recognizing situations where acoustic induced vibrations are indeed significant, and in such situations, how to best control them.
And the end of the tutorial, it is expected that the attendees should be equipped with clear notions about how acoustics waves might disturb a given system, how to quantify their contribution and when required, what are the technical options for mitigating the problem at hand.

Tutorial on Thermal Effects rescheduled for EUSPEN ICE 2021

Originally scheduled for EUSPEN International Conference and Exhibition at CERN 2020, the tutorial on Thermal Effects for Ultrastable Systems has been rescheduled to take place during ICE 2021 which will be hosted by TU Denmark in Copenhagen.

This tutorial will provide the framework required when designing mechanical systems with high immunity against thermal effects, i.e. temperature drifts and/or thermally induced elastic distortions. It will span basic and advanced concepts, practical evaluation tools and methods, as well as control strategies. A particular emphasis will be placed on the usage of an integrated approach, allowing to develop compact thermal elastic models sufficient to provide an understanding of the key parameters governing each problem. Such models can not only be used to decide on the severity of individual sources of disturbance but are also mandatory when designing practical mitigation solutions, either passive or active.

The approach will be illustrated with applications ranging from simple academic test cases and widespread components such as flexure-based translation stages, up to more advanced  opto-mechanical systems.

From these examples, it will be demonstrated that the design of high-performance systems relies on a  small set of concepts and rules, which can be effective for fulfilling ordinary or less conventional customers’ requests.

Intended audience: This is a beginning to intermediate level course, with material ranging from basic to complex, to provide both an overview and references for further study. The intended audience is graduates, postgraduate engineers/physicists, plus industry technical staff having a first experience in systems for which thermal stability aspects are relevant, and aiming at strengthening their insight so as to reduce guesswork for future projects.

Other tutorials are well worth of interest, check the euspen ICE 2020 website for reference:

Hello world

I have started this website while travelling with the ICE train 705 from Hamburg Hbf to Berlin Hbf. Thanks to Covid, it is really quiet here. Have a bit of patience before I get fully acquainted with the intricacies of WordPress. As always, customers come first!
