Dynamics

Natural Frequency Identification

This course will be a practical guide to the use of natural frequency prediction and computation to gain an intuitive understanding of the structure being analyzed. Both classical and finite element based approaches to frequency determination will be covered with the emphasis on understanding the driving factors of dynamic response. Kinetic energy, strain energy, and modal effective mass will be described through the use of real world engineering examples.

Random Vibration

This course will cover the topic of random vibration in engineering structures and how to predict responses to arbitrary random inputs. Random vibration power spectral density (PSD) inputs will be described with common inputs for various aerospace applications. The computation of rms and positive crossings will be described with related software tools to aid in the use of numerical results to compute fatigue life, maximum expected responses, and electronic component life.
