MNE 441 - Mechanical Vibrations

Credits 3
Lecture / 3 hours per week
Requirements: Prerequisite: EGR 242, 301; MNE Major Only
Discussion of generalized coordinates and the Lagrangian method of determining a system’s equations of motion. Normal modes and normal coordinates are introduced and the method of matrix iteration is used to find natural frequencies and modes. Free vibration of continuous systems is considered and techniques for finding natural frequencies are developed. Forced and transient responses of one degree of freedom systems are treated extensively, and forced response of multi-degree of freedom systems is discussed. Electrical analogies, use of the analog computer, and modeling of actual physical systems are discussed.
