Master Thesis: Vibration Transfer Path Analysis in Gearboxes through Oil-Structure Interaction: Experimental Investigation and Modeling

The Institute for Machine Elements and Systems Engineering researches the fundamental structural and tribological behavior of machine elements and represents this in experimentally validated model descriptions. These model descriptions are used to analyze and design the functional, loss, and structural behavior of complete technical systems, with a focus on drive technology. The developed models are also used for the research and development of methods in Model-Based Systems Engineering (MBSE) as a central element of future industrial product development processes.

As part of this work, experimental vibration analysis will be conducted on a gearbox test setup to measure the vibration transfer path from the gear to the gearbox housing, considering the interaction with the oil inside the gearbox. The influence of various parameters (e.g., oil level, gear speed) on vibration transmission will be investigated. Subsequently, a multibody simulation will be used to develop a dynamic model that represents this vibrational transfer behavior.

Tasks:

• Performing vibration measurements on a gearbox test rig to examine the vibration transfer from the gear to the gearbox housing
• Analyzing the measured data to evaluate the influence of key parameters on the vibration transmission behavior
• Developing a simplified multibody simulation model of the vibration transfer path
• Validating the simulation model by comparing its results with experimental data.

Requirements:

• Interest in the structural dynamic behavior of systems
• Basics of vibration analysis
• Prior experience in dynamic system modeling is an advantage
• Reliable and structured working approach

We offer:

• Future-oriented field of study
• Learning practical methods in structural dynamics
• Fast processing and intensive supervision
• Independent work organization and flexible hours
• Remote work possible via home office access
