Internship: Investigating the cause of negative eigen frequencies in pre-loaded structures

Mechanical engineering

In a nutshell


Veldhoven, Netherlands


No experience (Student)



Job Category

Mechanical engineering


Are you a Master student with experience in Mechanical Analysis and affinity with FEM? Then this apprentice internship could be interesting for you.

Job Mission

Within ASML, the sector Development & Engineering (D&E) is responsible for the specification and the design of the ASML lithography systems. The department Mechanical Architecture (MA) is designing, building and analyzing mechanical systems and sub-systems which are fitted into the end products. The group Mechanical Analysis is responsible for precision engineering of critical modules and for general mechanical analysis. Are you eager to further develop your mechanical expertise? To be part of the state-of-the-art technology innovation and multiple engineering discipline? If so, then an internship as mechanical analyst at ASML could be the perfect next step in your career.

Job Description

For this assignment you will join the FEM team of the Mechanical Analysis group. In this team, engineers use finite element approach to analyze different parts of the machine for their mechanical performance. In this assignment you will work on:
1) Understanding and theoretically explaining the causes of negative eigen frequencies in a pre-loaded (compression)modal analysis;
2) Understanding and theoretically explaining the causes of positive eigen frequencies in a pre-loaded (tension) modalanalysis;
3) Creating and validating the state space model of the pre-loaded component by checking if the static stiffness anddynamic behavior is correct.


You are a Master student in Engineering (Mechanical, Applied Mathematics, Mechatronics, Biomechanical, Aerospace and Civil). You are experienced with Mechanical analysis and have affinity with FEM. Experience with ANSYS, NX or Hypermesh is a plus. Furthermore, you have a strong analytical ability with a pragmatic attitude and a creative and logical thinking capability. In addition, you are a proactive student and are good in reporting. The English language is required, both written and verbally.

This is a Master apprentice internship for 5 days a week with a duration of minimum 4 months. The start date is as of September 2020.

Please keep in mind that we can only consider students (who are enrolled at a school during the whole internship period) for our internships and graduation assignments.

Other information

What ASML offers
Your internship will be in one of the leading Dutch corporations, gaining valuable experience in a highly dynamic environment. You will receive a monthly internship allowance of 500 euro (maximum), plus a possible housing or travel allowance. In addition, you’ll get expert, practical guidance and the chance to work in and experience a dynamic, innovative team environment.

ASML: Be part of progress
We make machines that make chips – the hearts of the devices that keep us informed, entertained and safe; that improve our quality of life and help to tackle the world’s toughest problems.

We build some of the most amazing machines that you will ever see, and the software to run them. Never satisfied, we measure our performance in units that begin with pico or nano.

We believe we can always do better. We believe the winning idea can come from anyone. We love what we do – not because it’s easy, but because it’s hard.

Students: Getting ready for real-world R&D
Pushing technology further is teamwork, and our R&D team is more than 5,500 people strong, with major sites on three continents. Dozens of diverse, interdisciplinary teams work in parallel to meet a challenging development schedule.

In such an environment, your colleagues may be sitting next door, or they could be thousands of kilometers away in a different country, or even working for a different company.

An internship at ASML is your opportunity to get to know this world of industrial-strength R&D and get a feel for that excites you most. Will you design a part of the machine, or make sure it gets built to the tightest possible specifications? Will you write software that drives the system to its best performance, or work side-by-side with the engineers of our customers in a fab, optimizing a system to the requirements of the customer?
