Doctoral student in modeling vehicle noise for sustainable transport

 

Royal Institute of Technology, School of Engineering

 

KTH is one of Europe's leading technical universities and an important arena for knowledge development. As Sweden's largest university of technical research and education, we gather students, researchers and faculty from around the world. Our research and education covers both natural sciences and all branches of technology as well as architecture, industrial economics, social planning, technical history and philosophy.

 

The ECO2 Vehicle Design research center located at the Department of Vehicles and Aerospace within the School of Engineering, is a multidisciplinary research environment focused on enabling resource-efficient vehicle construction in the future. Our main research focus is on the vehicle as part of the transport system, where we take into account the requirements as a hearing aid from different system levels. The ECO2 Vehicle Design Center brings together a wide range of expertise in vehicle concepts, lightweight construction, noise and vibration, vehicle aerodynamics, rail technology and vehicle dynamics.

 

The ECO2 Vehicle Design Center is working closely with the Swedish-based automotive industry and more information about the Center and its stakeholders can be found at www.eco2vehicledesign.kth.se .

 

duties

 

The ECO2 Vehicle Design Research Center is currently seeking a PhD student for a project focusing on vehicle noise modeling for sustainable transport in urban environments.

 

Noise is often a limiting factor for development of housing. So-called noise maps are used to assess the disturbance. Such noise maps provide equivalent noise levels, possibly distributed by day, night and weekend. All road vehicles undergo transit tests for broadcast audio levels as part of the certification process. However, it is well known that the degree of interference not only depends on sound levels, but knowledge of time variations, tone sounds, frequency content and other more complex characteristics of the audio is necessary to assess the degree of disturbance.

 

The aim of the project is to study models of environmental noise caused by road and rail vehicles in urban areas, as a tool in the development of new vehicle concepts and the basis for policies for increased transport efficiency. The work will cover steps from audio source to receiver:

  • Identification and characterization of sound sources on a vehicle, especially in the context of new propulsion (eg electrification) and operating cases (eg autonomous vehicles)

  • Sound propagation models that take into account details of vehicle proximity such as surface characteristics, wind, temperature, humidity, and impact of infrastructure (speed limitation, traffic lights, intersections, topology)

  • For this reason, study models for sound levels and sound characters in a realistic environment near road or track.

 

qualifications

 

For qualifications, a Master of Science degree in Technical Physics, Aerospace Engineering or other equivalent education relevant to the field is required, with a focus on acoustics, dynamics or flow mechanics along with numerical methods, and a pronounced interest in sustainability issues. In addition to traditional academic qualifications, one of the relevant qualification work, international experience and language skills is considered to be the merit.

 

The applicant should have a great interest in basic research and development. The service requires good ability to work independently and drive the project forward, to engage in new issues, to collaborate with other people in different groups.
