Vibration is an important consideration in many engineering applications, including compressors, turbines, gears, and bearings. Modal analysis is used to predict the natural frequencies of the structure. Knowing these frequencies, the engineer can design the structure to avoid resonance leading to catastrophic failure. You will explore the big ideas in modal analysis by extending 3D elasticity concepts then apply those big ideas to solve a practical problem in Ansys: predicting the natural frequencies and mode shapes for a turbine disk with blades.

Professor Bhaskaran will walk you through solving the “turbine disk with blades" example problem in Ansys. The geometry will be provided to you as a CAD file. As you set up and solve this vibration simulation in Ansys, you'll continue to refer back to the big ideas in modal analysis to make sense of the Ansys inputs and outputs. You will follow along in Ansys as Professor Bhaskaran demonstrates best practices for simulating vibration problems. Your final simulation will be a product of your own efforts and will give you the confidence to create reliable vibration simulations.
