Introduction to the project
Rolling resistance is the main key factor in measuring the energy efficiency of a tyre and has direct influence on the fuel consumption of a vehicle. A set of tyres of the green class "A" label compared to a "G" class can reduce fuel consumption by 7,5% of a passenger car. Tyre deformation constitutes a major part of rolling resistance and is mainly because of bending of the tyre crown at the leading and trailing edge of the contact patch and bending or bulging out of the sidewall because of the load on tyre structure, compression of the tread throughout the contact patch area and finally shearing of tread and sidewall elements. These phenomena cause a deformation induced viscoelastic energy loss in the tyre. They therefore dissipate energy in the form of heat whenever they are being deformed. In order to reduce the rolling resistance it is necessary to understand the mechanisms involved in tyre deformation when rolling. Extensive studies have been done in the past on the influence of temperature and frequency on the reduction of rolling resistance. The influence of the strain within the tyre is less studied although having a large influence on the rolling resistance; measured as tan d.
Goal and prototype deliverable of the project
For this assignment one particular component of the tyre; e.g. under tread should be optimized to give an improvement in rolling resistance. The optimization of the tan delta versus strain of this particular compound should be performed by means of Design of Experiments (DoE). The DoE will include material as well as processing parameters. At the end of the design a prototype tyre should be built with the optimized compound and checked on performance improvement.
We are searching for the best MSc graduated candidates in material development. Candidates should have a strong and demonstrable interest in elastomers and dynamic properties. Additionally, they should have affinity with tyre properties and performance.
You need to be willing to enter a career in tyre R&D, as a successfully finished PDEng trajectory is linked to an appointment at Apollo.
Important professional skills are English language skills, communication and interpersonal skills both with academics and professionals, and you should be a pro-active and result oriented team worker in an industrial as well academic environment. Besides, you will be a member of an international group.
Please send your letter of motivation, with a curriculum vitae, a list with grades of courses attended, references and, if applicable, a list of publications through the link below before 31 March 2017.
If you have any further questions about the PDEng programme in Energy and Process Technology, please contact Gerrit Brem: firstname.lastname@example.org
General information about PDEng programmes you can find at our website
The candidate will be appointed by the company Apollo Tyres Global R&D BV. Apollo Tyres offers you a contract for 24 months. During these two years, you follow a tailor-made post-master design programme with a combination of education (~50% within the PDEng programme in Energy and Process Technology of the University of Twente) and working on a design project (~50%). The salary will be € 1.828 gross per month. Additionally, Apollo Tyres provides excellent facilities for professional and personal development, a holiday allowance and an end-of-year bonus.
On successfully completing the programme, you will receive a certified degree. You will be entitled to use the academic degree Professional Doctorate in Engineering (PDEng) and will be registered as a Technological Designer in the Dutch register kept by the Royal Institution of Engineers in the Netherlands (KIVI).
Besides, you will get a job offer from Apollo if this PDEng trajectory was successful from an educational, design as well as social background.
The University of Twente. We stand for life sciences and technology. High tech and human touch. Education and research that matter. New technology which drives change, innovation and progress in society. The University of Twente is the only campus university in the Netherlands; divided over five faculties we provide more than fifty educational programmes. The University of Twente has a strong focus on personal development and talented researchers are given scope for carrying out pioneering research.
The Faculty of Engineering Technology (ET) is one of the five faculties of the University of Twente. ET combines Mechanical Engineering, Civil Engineering and Industrial Design Engineering. Our faculty has approximately 1800 bachelor and master students, 400 employees and 150 PhD candidates. The departments of the faculty cooperatively conduct the educational programmes and participate in interdisciplinary research projects, programmes and the research institutes: MIRA, CTIT, SBE and IGS.
