Vibration engineering helps you control vibration in engineering systems and in everything from consumer product development and design, manufacturing, aerospace and automotive systems, and more.
Engineers with skills in vibration engineering contribute to creating manufacturing production systems, aerospace systems, automotive engineering, medical product development, consumer product development, and a host of industrial equipment and process systems in which vibration must be minimized or controlled.
The Impact of Machine Vibrations
Vibrations generated by machines and equipment can be disruptive and disturbing. Engineers often seek to reduce vibration so they can increase the durability and reliability of a machine, machinery system, or product; eliminate stress on a structure; and/or reduce damage, abnormal stoppage, or catastrophic failure. Targeted vibration prevention is the goal of a vibrations engineer.
The advanced certificate in vibrations takes you beyond the preparation in vibration engineering that you would typically complete during your undergraduate program of study. In this collection of graduate level courses, you will learn to use sophisticated software tools, analytical techniques and experimental methods to design, develop, and implement solutions for problems of vibration control and minimization in engineering systems. You will also be exposed to modern technologies used in industry to ensure that you are prepared for today's highly specialized job market. The curriculum answers a need for graduate-level instruction for practicing engineers in a field of importance for the 21st century.
What is a Graduate Certificate?
A graduate certificate, also called an advanced certificate, is a selection of up to five graduate level courses in a particular area of study. It can serve as a stand-alone credential that provides expertise in a specific topic that enhances your professional knowledge base, or it can serve as the entry point to a master's degree. Some students complete an advanced certificate and apply those credit hours later toward a master's degree.
Is concerned with analytically finding the dynamic characteristics (natural frequencies and mode shapes) of vibratory mechanical systems (single-degree and multi-degrees of freedom systems), and the response of the systems to external excitations (transient, harmonic, and periodic). Application to vibration damping techniques (Dynamic Vibration Absorbers) is also covered. In addition, laboratory exercises are performed, and an independent design project is assigned. (Prerequisites: MECE-320 or equivalent course or graduate standing in the MECE-ME or MECE-MS program.) Lecture 3 (Fall).
This course trains students to utilize mathematical techniques from an engineering perspective, and provides essential background for success in graduate level studies. An intensive review of linear and nonlinear ordinary differential equations and Laplace transforms is provided. Laplace transform methods are extended to boundary-value problems and applications to control theory are discussed. Problem solving efficiency is stressed, and to this end, the utility of various available techniques are contrasted. The frequency response of ordinary differential equations is discussed extensively. Applications of linear algebra are examined, including the use of eigenvalue analysis in the solution of linear systems and in multivariate optimization. An introduction to Fourier analysis is also provided. (Prerequisites: (MATH-241 and MATH-326) or graduate student standing in the MECE-MS or MECE-ME programs.) Lecture 3 (Fall, Spring).
Advanced Engineering Mathematics
Advanced Engineering Mathematics provides the foundations for complex functions, vector calculus and advanced linear algebra and its applications in analyzing and solving a variety of mechanical engineering problems especially in the areas of mechanics, continuum mechanics, fluid dynamics, heat transfer, and vibrations. Topics include: vector algebra, vector calculus, functions of complex variables, ordinary differential equations and local stability, advanced matrix algebra, and partial differential equations. Mechanical engineering applications will be discussed throughout the course. (Prerequisites: MECE-707 or equivalent course or graduate student standing in MECE-MS or MECE-ME.) Lecture 3 (Fall, Spring).
Intermediate Engineering Vibrations
Is concerned with analytically finding the dynamic characteristics (natural frequencies and mode shapes) of continuous mechanical vibratory systems (strings, rods, and beams), and the response of the systems to external excitations (transient and harmonic). Solutions using the finite element method is also introduced. (Prerequisites: MECE-658 or equivalent course or graduate student standing in MECE-MS or MECE-ME.) Lecture 3 (Spring).
Choose one of the following:

(Prerequisites: EEEE-707 or equivalent course.) Lecture 3 (Fall, Summer).
This course is designed to introduce the student to advanced systems modeling techniques and response characterization. Mechanical, electrical, fluid, and mixed type systems will be considered. Energy-based modeling methods such as Lagrange’s methods will be used extensively for developing systems models. System performance will be assessed through numerical solution using MATLAB/Simulink. Computer projects using Matlab/Simulink will be assigned and graded in this course including concepts of data analysis and how it performs to parameter estimation. Linearization of nonlinear system models and verification methods are also discussed. (Prerequisites: MECE-320 or equivalent course or graduate standing in the MECE-ME or MECE-MS program.)
