The injury of the dorsal root ganglions (DRG) of the nerves in the human neck has been commonly reported owing to the rear-end collisions of motor vehicles. Research of the DRG-damaged process will be beneficial for designing motor vehicles with high safety. According to our study, one of the potential …

Electrification of vehicles has a good momentum today. However, energy consumption of electrified vehicles is not very much in focus, instead the society is just happy for the electrification to take place. In the future, however, the focus on the energy efficiency of electrified vehicles will for sure be intensified. …

Modern ventilation systems are often driven by isolated centrifugal fans which produce tonal and broadband noise. Exposure to tonal noise for a long-term can affect human bodies. It affects autonomous and hormonal systems in the body, which can lead to diseases such as high blood pressure, hearing  loss and cardiac …

Electric aircraft become highly attractive in recent years owing to the advantage of zero greenhouse gas emissions such as CO2 and NOx, which are unavoidable for the use of fossil fuels. The propulsion systems of these aircraft are driven by electricity. Hence, battery technology is the primary factor limiting the …

The overreaching goal of the proposed project is to advance the use of aeroacoustics simulations of vehicles and develop suitable sound propagation methods for application to challenges in urban environments. Examples of such challenges are high-speed rail systems generating flow-induced noise with impact on urban environments and in the end …

Project title: Prediction of External Flow Acoustic Impact on In-cab Noise Project period: 2014-12-01 — 2018-12-31 Funding body: Fordonsstrategisk forskning och innovation (FFI) of VINNOVA Grant number: 2014-01386     Introduction to project contents: A quiet cabin environment is a common concern of automotive and aeronautic industries to manufacture high-class …

As a new way for transportation, electric aircraft have been attracting extensive attention due to no CO2 emissions in operation. However, noise emission is crucial for electrical aircraft to be accepted to transport in urbans. Electric propulsion systems therefore need to be improved to reach this goal. Since the propellers of …

Purpose and goal: The purpose of the multidisciplinary project is to develop industry adapted tools and best-practice guidelines to computationally couple fluid and structure dynamics (aeroelasticity) as well as aeroacoustics with the aim to introduce this multidisciplinary technique in an industrial aeronautical context, contribute with scientific publications and actively contribute …
