Introduction

Are you a master student with background in Mechanics? Do you have affinity with design for experiment, measurement system and data analysis? Then this internship could be interesting to you!

Background Information

Within ASML stability of bolt connections are very important and often no slip is acceptable. Therefore prediction of the pretention, over 7 years, is very important. To improve the predictability a better understanding of setting is needed. After tightening, bolted connections are subject to bolt pre-tension force loss, also known as setting. ASML predicts setting using industry standard models. These models are conservative and give an over-estimation of the setting. This conservatism limits the bolted connection design in the balance between volume, mass and connection loads.

Your Assignment

The goal of this internship is to provide a detailed setting model based on ASML proposed models or any other analytical model. Analytical approach proposed by ASML brings differential equation with several unknown parameters. Analytical or numerical solution for such equations is needed. Unknown parameters can be found out of matching solution to experimental data. Experiment, measurement system and data analysis should be developed. Final analytical model needs verification with measurements and data analysis for parameters in model: material combinations of bolt and clamped material, bolt length, temperature and any other parameters taken into the model.

Your Profile

  • You are a master student with background in Mechanics.
  • You have the ability to solve analytical and numerical equations.
  • You have affinity with design for experiment, measurement system and data analysis.
  • You are available for minimum 6 months (preference 1 year) and for 4-5 days per week.
  • You are available to start as soon as possible

Please note that we can only consider students who are enrolled at a school for the entire duration of the internship.

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 based on your educational level and number of days per week, plus a possible housing or travel allowance. More information on the allowances can be found on our website. In addition you will 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 applications 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. At ASML we are always pushing technology further.

Students: Getting ready for the real-world
Teamwork is key within ASML. Our R&D team is more than 5,500 people strong and worldwide we form one big team with over 25,000 employees. These colleagues have 123 different nationalities and work at our major sites on three continents.

Dozens of diverse, interdisciplinary teams work in parallel to meet a challenging development schedule. In this inspiring 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 and get a feel for that excites you most. Use your education, gain real-life working experience and explore the world of high-tech – all at the same time.
