Mechanical Vibrations (4 cr)

Objectives (course unit)

The students understand the laws governing the dynamical behaviour of mechanical systems and can utilize them to avoid problems caused by vibration.

Content (course unit)

Basic concepts and mathematical models in vibration analysis. The components of a discrete vibrating system. The natural and forced vibration of single degree-of-freedom system. The equations of motion of multiple degree-of-freedom system using the Newton’s and Lagrange’s equations. The natural and forced vibration of multiple degree-of-freedom system. Isolation and damping of vibrations.

The student knows the basics of dynamic behavior of rigid body strutures and is able to use his/her skills to analyse vibration problems and to avoid mechanical vibration problems. The student will be able to form the basic formulas for analysing the vibration and forces and moments in rigid bodies in case of discrete systems (one d.o.f.) without damping and free or forced vibration.
Takes responsibility for his/her own work.
