    This class was tough.

    Course Overview:

    I highly recommend the course as this mechanical vibration course was one of the most difficult courses but absolute essential course if you’re to be a mechanical or aerospace engineer dealing with dynamic moving objects. The5 labs held were representative of how functional testing compared to the predictive control model response of dynamic systems. The professor spent time to tutor students even outside of his normal working hours and never once even opened the textbook for his lectures or his notes, unless he had to read the question on a homework problem for a student. Besides teaching vibration and graduate courses, he’s also worked on some amazing thesis projects with his graduate students associated with dynamic problems.

    Course highlights:

    I learned a lot about what causes an object to become unstable/stable with pole calculation, how external energy source causes fluttering on a vehicle or oscillation within a vehicle, how to calculate the natural frequency of a system, phase angles, effects of what a viscous damping oscillation response looks like. It also goes into through detail what position of an oscillating object causes something to be stable or unstable. Transfer function, stability calculation, and type of damping system (critical damping, underdamping, and critical damping) is paramount to learning how to develop control models.

    Hours per week:

    12+ hours

    Advice for students:

    Review your eigenvalues well from your linear algebra and differential equations before you enter this course. You’ll need this in order to perform modal decomposition for the response solutions. Laplace transform is also crucial in order to find the step function r response. Try to pick up all the old exams along with the solutions from the instructor and practice working those problems repeatedly. The instructor has nearly 10 years worth of exams which you can practice. Each problem case at first looks unique, but the principles are the same regardless.
