Course Objectives The objective of this course is to introduce the vibrations in mechanical systems, which are concerned with the oscillatory motions of bodies and the forces associated with them. The course provides with an understanding of the nature and behavior of dynamic engineering systems and the capability of applying the knowledge of mathematics, science, and engineering to solve engineering vibration problems.
Learning Outcomes The students who succeeded in this course;
  • Develop mathematical models of dynamic systems
  • Obtain the analytical solution for the time response of the system
  • Calculate natural frequency and mode shapes of vibrating mechanical systems
  • Propose solutions concerning vibration isolation and control in dynamic systems
  • Employ numerical techniques in analysis of dynamic systems
Course Description The course covers vibrations of systems with single degree of freedom, multiple degrees of freedom, and of continuous systems, structural damping models, Lagrange’s Equations for vibration analysis, modal analysis, vibration analysis of free or excited mechanical systems by numerical techniques, and vibration isolation and active control of vibration in industrial applications.
