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 study impact loads and fatigue, and you are able to apply this knowledge in the design of axles. You will be able to take into account economic and sustainability objectives in vibration and fatigue design.

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.
