1. NVH analysis and optimization of electric powertrain
University essay from KTH/Maskinkonstruktion (Inst.)Abstract : With increasing focus on electromobility many companies are developing vehicles powered by an electric energy source. Previously, engines used to be the most prominent source of noise in a traditional Internal Combustion Engine (ICE) vehicle. READ MORE

2. Role of damping in NVH CAE procedures
University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknikAbstract : Automotive manufacturers currently face a challenge with expeditious enhancement of the vibro-acoustic properties of their vehicles. A major reason for this setback is the limited design information available during initial development stages added with limited knowledge of damping within complex structures. READ MORE

3. Vibro-acoustic monitoring for in-flight spacecraft
University essay from Luleå tekniska universitet/RymdteknikAbstract : The concept of using the vibration transmitted through the structure of space systems whilst they are in flight for monitoring purposes is proposed and analysed.The performed patent review seems to indicate that this technique is not currently used despite being, in principle, a good way to obtain valuable knowledge about the spacecraft’s condition.

4. Transfer Path Analysis of a Passenger Car
University essay from KTH/MWL Marcus Wallenberg LaboratorietAbstract : Even though there are no regulations on the interior noise level of passenger cars, it is a significant quality aspect both for customers and for car manufacturers. The reduction of many other car noise sources pushed tyre road noise to the forefront. READ MORE

5. Electromagnetical model of an induction motor in COMSOL Multiphysics
University essay from KTH/Elektrisk energiomvandlingAbstract : Ansys, Flux or COMSOL are examples of software-tools that can be used to study magnetic noise, caused by magnetic forces in the air-gap, in induction motors. The project team wanted to use COMSOL in this thesis. The electromagnetical domain needs to be coupled to the mechanical domain to complete the study. READ MORE
