Jobbtitel: PhD student in Solid and Structural Mechanics

Arbetsbeskrivning:
Information about the research/the project/the division/department Switches and crossings (S&C) are a central part of railway networks as they allow for trains to change between tracks. The flexibility comes at a cost however as the variation in rail profile shapes along S&C cause higher dynamic loads than in regular track. These in turn cause degradation and failures that result in high maintenance costs and traffic disturbances. It would thus be beneficial to enhance the condition monitoring of S&C to provide the information needed for better and more cost efficient maintenance and to provide a basis for system optimization. The objective of this project is therefore to develop a model based procedure that can identify the structural condition of switches and crossings via data from sensors embedded in track. The intention is that the system should be accurate enough such that maintenance decisions can be taken based on output from this routine.  This research will build on previous investigations in European and in-house CHARMEC projects (see www.chalmers.se/charmec). It will be run in close cooperation with industrial partners - especially Trafikverket (The Swedish railway administration) - and will be included in European research projects. The project will be at the Division of Dynamics, Department of Mechanics and Maritime Sciences (see http://www.chalmers.se/en/departments/m2/research/dynamics). The Division of Dynamics currently has 15 faculty members and 8 PhD students. The present research activities are focused on mechanical systems, structural dynamics, wave propagation, and railway mechanics. Areas of interest relate to various problems in solid mechanics such as vibrational problems, fatigue, wear, contact mechanics, wave propagation, optimization and dynamics of smart materials and structures.  Your project will be part of the activities within the Swedish National Centre of Excellence in Railway Mechanics CHARMEC – CHAlmers Railway MEChanics (see http://www.chalmers.se/charmec). CHARMEC was established in 1995 and is supported by Chalmers, the Swedish Transport Administration (Trafikverket) and an Industrial Interests Group comprising ten partners. All research at CHARMEC is carried out in an international context with overall objectives to reduce the railway's costs for production, operation and maintenance, and to decrease the environmental footprint while improving safety, reliability and transport quality. Currently, some 25 research projects are carried out within CHARMEC. Major responsibilities Your major responsibilities as PhD student is to pursue your own doctoral studies. This includes developing scientific concepts and communicating research results. The position is a full-time temporary employment with a time limited to a maximum of 4.5 years including teaching or other department duties corresponding to 15% of working hours. You will be employed by Chalmers and will receive a salary according to current salary agreements. Position summary Full-time temporary employment. The position is limited to a maximum of 4.5 years. Qualifications A suitable background is a Master of Science (Swedish: civilingenjör) in mechanical engineering, civil engineering or engineering physics with emphasis on structural dynamics, solid mechanics and computational methods. The position requires oral and written communication skills in English and Swedish. If Swedish is not your native language, you are expected to teach tutorials in Swedish after two years. Chalmers offers Swedish courses. Application procedure The application should be marked with Ref 20180471 and written in English. The application should be sent electronically and be attached as pdf-files, as below: CV: (Please name the document: CV, Family name, Ref. number) • CV • Other, for example previous employments or leadership qualifications and positions of trust. • Two references that we can contact. Personal letter: (Please name the document as: Personal letter, Family name, Ref. number) • 1-3 pages where you introduce yourself and present your qualifications. • Previous research fields and main research results. • Future goals and research focus. Are there any specific projects and research issues you are primarily interested in? Other documents: • Copies of bachelor and/or master’s thesis. • Attested copies and transcripts of completed education, grades and other certificates, eg. TOEFL test results. Please use the button at the foot of the page to reach the application form. The files may be compressed (zipped). Application deadline: 3 October, 2018 For questions, please contact: Assistant Professor Björn Pålsson, Dynamics, bjorn.palsson (at) chalmers.se, +46 31 772 1302
