Vibrations

Module description:

valid for matriculations after 2012

Lecturer: Prof. Dr.-Ing. habil. Emil Kolev

Teaching language:English

Contact hours/credits: 4 hour per week, 5 credits (ECP)

Course objectives:

• This course covers the basics of vibration technology

• The students should be able to handle the vibration behaviour of mechanical systems analytically and to detect and understand vibration phenomena in practice

Teaching method: Lecture

Grading: written examination (90 min)

Work load: Presence 60 h + self study 90 h = 150 hours = 5 Credit Points

Course contents:

• Classification of vibrations:

• lumped and continuous parameters

• Linear systems with a single degree of freedom

• Undamped systems with free behaviour:

• longitudinal oscillator

• torsional oscillator

• Damped systems with free behaviour

• Forced, damped vibrations

• Vibration with force excitation at:

• the mass

• the spring

• the damper

• the housing

• Multibody longitudinal oscillator

• Continuum

• Mechanics:

• longitudinal vibrations of bars

• torsional vibrations of bars
