Learning Objectives:

The students are familiar with the basics of sound and vibration. They know how they are generated, how they are perceived by human beings, and which requirements are given by vehicle users and the society. Using the example of ride comfort, student have get to know basic approaches to reduce noise and vibration by an appropriate combination of elastic, damping, and inertial elements. They are ready to apply different tools and procedures, to do calculative and experimental analysis of dynamic vehicle systems and to interpret the results adequately.

Content:

1. Perception of sound and vibration

2. Fundamentals of acoustics and vibration

3. Tools and methods for measurement, calculation, simulation, and analysis of sound and vibration

If possible, an excursion will be offered which gives insights in the development practice of a car manufacturer or a system supplier.
