Objective

The designer of a dynamic structure must take care that the structure will not vibrate catastrophically. On this course you will learn to calculate the natural frequencies of structures and you will understand their importance in forced vibration. You will also learn to design simple structures so that the resonance effect is avoided. You will also recognize vibrating systems with multiple degrees of freedom.

Knowledge and understanding: You understand the theoretical concepts in machine dynamics.

Engineering Practice: You know how to calculate natural frequencies and are able to apply this information in your designs.

Content

Introduction and refresher lessons on dynamics. Components of a vibrating system. Undamped and damped natural vibration of one degree of freedom. Undamped and damped forced vibration of one degree of freedom. Balancing. Isolation of vibration. Motion equations of multiple degrees of freedom and undamped natural vibration.
