Where there are forces and motion, there is dynamics. As such, the field of dynamics is one of the oldest fields of science, which started from Newton’s analysis of planetary motion and is now applied in almost every technological area. Especially in the field of precision engineering, dynamics and control face many challenges.

High precision combined with high speed
At the large scale, high-tech systems require precision to be extended toward the nanometer and even picometer range, e.g. for volume production, automotive and space applications. This is increasingly difficult because at the same time these systems need to operate at the highest possible speeds, causing large and high-frequency excitations. At the same time, external noise sources need to be damped to prevent undesired vibrations.

Accuracy combined with mass
On the other hand at small scale, micro and nanoscale devices for sensing and actuator applications in e.g. mobile and medical applications, are required to meet increasingly accurate readout and control, while operating in the MHz range due to their small mass.

A workshop you don't want to miss
The Dynamics for precision engineering workshop focuses at providing a current, educational overview of the challenges and solutions that involve dynamics at all length scales, bringing together scientists and engineers from both industry and academia.

Welcome and introduction to the programme - Dynamics at the nanoscale: new materials, physics and devices

Peter Steeneken, Hoogleraar Dynamics of Micro and Nanosystems, TU Delft

Although the field of dynamics was initiated by the study of celestial bodies, technological advances have now enabled us to study the motion of systems at the micro and nanoscale. At these scales frequencies become higher and masses smaller, and different physical laws dominate the dynamics. This presentation will outline the challenges in dynamics at these atomic scales, and show how nanomaterials like graphene enable new sensor concepts.

A collapse-mode CMUT-array for pre-clinical imaging: semi-analytic modeling and experiments

dr.ir. R.H.B. (Rob) Fey, Associate Professor (Universitair Hoofddocent), Technical University of Eindhoven

In cooperation with Philips Research and Erasmus MC, a semi-analytic model has been developed for a fluid-coupled transmitting Capacitive Micromachined Ultrasound Transducer (CMUT) array operated in collapse-mode, which is intended to be used in catheters for pre-clinical imaging. The static response of a single CMUT cell and the dynamic response of a single CMUT cell and a CMUT array are analyzed. Measurements show that the static behavior is predicted with high accuracy. Satisfactory correspondence is obtained between the predicted and measured dynamic behavior of the CMUT array. It is concluded that the presented model allows for fast parameter studies and is a powerful tool for CMUT pre-design.

Tackle pm vibration in a cryogenic application on an Electron Microscope

Ab Visscher, Senior Expert Dynamics and Construction, FEI / Thermo Fisher Scientific

The Technique of Energy Dispersive X-ray Spectrometry on an Electron Microscope makes it possible to do local identification of materials, down to individual atoms. The technique requires detectors that must be cooled down to cryogenic temperatures. This energizes small disturbing vibrations to the sample, only 10 pm at 270Hz. How can vibrations of a mere fraction of typical atomic distances still be problematic? How do we measure sub-atomic vibrations? A tough quest will be presented to the cause and transmission path of this tiny vibration, and the solution.

Acoustically induced vibrations and acoustic shielding of high precision machinery

Bert Roozen, Owner, NOVIC Noise and Vibration Control & guest professor at KULeuven

Structural vibrations in high precision machinery can have disastrous effects on machine performance like wafer steppers and electron microscopes. Even minute vibrations cause the wafer to be incorrectly illuminated which reduces the positioning accuracy of the pattern on the wafer. Similarly, electron microscopes can suffer from vibrations causing a blurring image.

The presentation focusses on acoustically induced vibrations. The response of structures under acoustic excitation will be addressed from both a theoretical and experimental point of view. It is shown that design principles from the field of noise control engineering can be used to reduce acoustically induced vibrations. Finally, sound fields generated by the machine itself will be addressed.

A simulation framework for predicting machine damage due to seismic events

Ronald Ruimerman, Mechanical Analyst, ASML

Seismic events may cause damage to ASML lithography machines. This can lead to downtime and high costs. The occurrence of damage is difficult to predict. Experiments are not feasible and for simulations it is a challenge to obtain a proper level of accuracy without increasing computation times to unpractical levels. In the current work a simulation framework is proposed to overcome these challenges and to mimic machine behavior due to actual earthquakes. It can be applied to validate/improve current seismic design criteria, but also to analyze safety concepts to make the machine more resistant to structural failure.

Experimental dynamics in automotive industry

Maarten van der Seijs, Co-founder / Head of Technology, VIBES.technology

Recent developments in the automotive industry lead to higher demands on sound and vibration performance. In order to engineer sound and vibrations accurately and in an early phase of development, new technology is needed than copes with higher frequencies (due to electric drivelines), modularity and multi-domain modelling. Dynamic Substructuring provides a solution for these challenges, allowing to assemble experimental and numerical models of subsystems to simulate full vehicle behaviour. Some new techniques in this field will be presented using real-life engineering cases.

Dynamics in Space Instrumentation

Floris van Kempen, Optimization specialist, TNO Optomechatronics

Space instrumentation is used for Earth Observation, Planetary exploration, astrophysical measurements and astronomical observations. Launch Loads and in-orbit dynamic loads might impact the structural integrity and stability of these instruments. In this presentation, methods will be presented to predict the impact of various dynamic loads on the systems performance of space instrumentation. Furthermore, verification of predicting methods will be discussed.
