Mechanical Vibrations

ME56300

Credit Hours: 3

Learning Objective:
Upon successful completion of this course, you will be able to understand basicand intermediate concepts necessary for the analysis of the dynamics of complex structures under various loading conditions. In particular, you will be able to:
  • Explain and correlate the structural properties of complex structures to the overall vibration characteristics in order to design systems having required dynamical properties.
  • Apply theoretical and numerical procedures to predict the dynamic response of discrete or continuous structural systems under the most diverse loading conditions.
  • Develop reduced order models to treat systems with a large number of DOF.
  • Understand and implement approximate methods for the numerical solution of distributed parameter systems.
  • Understand the main features of the dynamics of nonlinear lumped parameters systems.


Description:
The course will cover fundamental concepts on the vibration of mechanical systems including, but not limited to, review of systems with one degree for freedom, Lagrange's equations of motion for multiple degree of freedom systems, introduction to matrix methods, transfer functions for harmonic response, impulse response, and step response, convolution integrals for response to arbitrary inputs, principle frequencies and modes, applications to critical speeds, measuring instruments, isolation, torsional systems, introduction to nonlinear problems. Fall 2016 syllabus
