BASIC INFORMATION

Time and Place: MWF 3rd Period, MAEB-229.

Instructor: Raphael T. Haftka (haftka@ufl.edu) 220 MAE-A. Office hours: MWR 3-4PM.

Teaching Assistant: Jian Liu ljian99@ufl.edu 211 Benton. Office hours TRF 2-3PM.

Textbook: Meirovitch, L., Fundamentals of Vibrations,

Objective: Introduce students to analytical and numerical methods in structural dynamics with emphasis on vibration and to opportunities to optimize system for desired dynamic response.

Catalog Information: Vibration analysis and synthesis of continuum and multidegree of freedom lumped parameter systems. Computatonal and experimental techniques in modal analysis. Prerequisite:EML4220, or equivalent.

Topics:

  • Review of the response of single-degree-of-freedom systems to initial and to harmonic excitations.
  • Response of single-degree-of-freedom systems to non-periodic excitations.
  • Elements of structural dynamics, including virtual work, D’Alembert and Hamilton principles and Lagrange equations.
  • Multi-degree-of-freedom systems
  • Exact solutions for distributed parameter systems
  • Approximate methods for distributed parameter systems

 

COURSE ASSESSMENT

Homework: Homework assignments help students absorb methodology and concepts taught in the course and prepare them for the project and exams. There is 20% bonus for homework done by a word processor with detailed explanations at the level of posted solutions. Homework cannot be submitted after a solution is posted, typically 2 days after it is collected. Homework may be submitted with no late penalty by 5PM on the day due (put in TA’s mailbox). After that, there is 10% penalty per day.

Exams: In-class exams are closed book, except for one 8.5"x11" page, written in any density (student may bring a magnifier).

Grading Policy: 25% homework, 40% mid-term exams, 35% final exam. Grades are on a absolute scale (A=91+, B+=86+, B=81+, etc.). Predicted grades, based on homework and progress to date are posted during the semester beginning after the first in-term exam.

Academic honesty: All students admitted to the University of Florida have signed a statement of academic honesty committing them to be honest in all academic work and understanding that failure to comply with this commitment will result in disciplinary action. This statement is a reminder to uphold your obligation as a student at the University of Florida and to be honest in all work submitted and exams taken in this class and all others.
