Intended learning outcomes

The objective of the course is to familiarize the student with fundamental laws in mechanics of vibration, and to give the student the proficiency needed to independently apply these laws to vibration problems. After completed the course, the student is able to:

• model simple and more complex mechanical systems;
• understand definitions and fundamental concepts used in mechanics of vibrations, e.g. velocity, acceleration, energy, frequency, period and damping factor;
• use modal analysis, solve eigenvalue problems and determine frequencies and eigenmodes for different structural elements;
• use Lagrange’s equations to derive the governing equations for a vibrating system;
• solve the governing equations analytically and numerically;
• perform simpler analyses for stability of non-linear systems;
• derive simpler theorems used within mechanics of vibration.
