Research assignment – R&D – Measurement accuracy of a rubber characterization test setup
A test setup has been designed and developed at VMI to determine some rheological characteristics of non-vulcanized rubber compounds. In this setup, a test chamber is filled with rubber compound using a small extruder. The required torque to rotate a cone in this filled test chamber is measured. This torque is a measure for the viscosity of the rubber compound. These measurements are used to make a material model to be used in Computational Fluid Dynamics (CFD) simulations. The current test setup does, however, has its limitations in terms of maintenance, data reliability and the range of parameters that can be extracted from the data.
We are looking for a student to improve the measurement accuracy of our test setup for rubber compounds.
Measurement accuracy is referring to the absolute accuracy; does the setup measure the ‘true’ value. Additionally, this accuracy refers to the variation in measurements if we repeat the measurement multiple times.
The R&D Rubber Process & Tire Technology department of VMI is looking for an intern to complete a research assignment on improving the measurement accuracy of our test setup.
The R&D department Rubber Process & Tire Technology (RPTT) serves as a research and technology group to support other departments within VMI in topics related to rubber processing and tire technology. In that role RPTT researches current and potential promising topics relate to processing rubber compound. It additionally supports product groups to make the right design decisions to shape rubber in the right way in their machines.
You will be part of a team of 3 rubber process specialists to improve the accuracy of simulations.
As an intern at VMI, you will work on improving the measurement accuracy of our test setup to characterize rubber compounds. You will work on the following activities:
- A critical review of the current setup to understand its functionality;
- Performing multiple trials on the setup to understand the main sources of measurement uncertainty;
- Proposing, conceptualizing and implementing design changes, if necessary, to improve the measurement accuracy;
- Defining a proper maintenance protocol to maintain the measurement accuracy over time;
- Studying the improved measurement accuracy using a well-defined test program;
- Documenting the assignment in a report.
- You are an hbo/wo student in Mechanical Engineering;
- You are currently in the final year of your studies;
- You are looking for an internship of 40 hours per week. For this internship, it is possible to be working partly at home on the assignment.
- You are creative, proactive, solution-oriented, analytical and research oriented person;
- You have a background in designing mechanical systems;
- Knowledge of (rubber) polymers is a pre.
We give you the opportunity to join a cozy team for six until nine months. You will have the opportunity to carry out challenging research in which you can add real value to the organization. For this internship you will receive an internship allowance and a travel allowance.
In addition to our own internship program, you will have the opportunity to participate in a Master Class at Perron038.
These Masterclasses are organized each time by different companies and relate to soft skills, but can for example also be about LinkedIn, project management and job application tips.
VMI is one of the partners at innovation center Perron038 in Zwolle. Various technical companies work together here in the field of Technology and they share knowledge and experiences with each other in an inspiring environment. At the training sessions & Tuesday afternoon drinks at Perron038 you will also meet students from the other companies in the region. Want to know more about Perron038? Read more
With your internship at our company, you make a valuable contribution to our organization. Your input and ideas help us achieve our goals and improve our services.
As an intern, you will bring:
- A fresh perspective and new ideas that help us improve our processes;
- An opportunity to inspire and motivate our employees with your enthusiasm and energy;
- A chance to enrich our culture and values with your unique perspective.
