Thesis work: Influence of propeller pressure pulsations on hull vibrations and structure-borne noise
Technology, Data & Digital · Software & Web Development · Software Engineering
In short
This thesis work at Volvo Penta in Göteborg, Sweden, focuses on investigating how propeller pressure pulsations affect hull vibrations and structure-borne noise. The student will conduct literature studies, FE modeling, and acoustic simulations to compare vibration contributions and potentially develop a simplified calculation method.
Responsibilities
- Investigate how propeller pressure pulsations transfer into the boat and contribute to hull vibration and structure-borne noise.
- Conduct a literature study on propeller pressure pulsations, hull vibration, and noise, including the added-mass effect.
- Perform FE modeling of an example hull and map CFD pressure results onto the structure.
- Compare the vibration contribution from pressure pulsations versus the gearbox path.
- Develop a simplified method for accounting for the phenomenon, if feasible.
- Perform acoustic simulation of the engine room.
Requirements
- Knowledge of solid and fluid mechanics
- Knowledge of Finite element method
- Knowledge of Structural dynamics and vibrations
- Knowledge of Acoustics
- Knowledge of Hydrodynamics
- Master (30 ECTS points) level thesis
- Fluent in Swedish or English
Desired Qualifications
- Preferred masters program: Applied Mechanics
Benefits
- Opportunity to shape sustainable transport and infrastructure solutions.
- Work with next-gen technologies and collaborative teams.
- Gain experience at a world-leading supplier of engines and power systems.
- Access to CAE and NVH departments with simulation models and measurement capabilities.
- Work at the Volvo Penta Marine Test Center.
