# Simulation Examples, Homework, and Quiz

### Simulation Examples

Several simulation examples are provided here. Each of them comes with a description file, video instruction, and Ansys simulation file. All of the simulations are conducted using Ansys Mechanical. Download the student version of Ansys software from here.

#### (1) Drum cymbal MSUP transient analysis

Let's revisit this drum cymbal analysis. Explore the simulation and try the transient analysis using different modal shape results. How does the result change?  Download the zip file and extract the contents. Go through the Readme file. Follow along with the provided How To Video file.

#### (2) A commercial drone arm bending due to hard landing

When a commercial drone hits the ground from a hard landing, it is likely that its arm will bend due to the high inertia force. It is important to investigate the amount of deflection and control it within an acceptable range. Check out this simulation and find out how MSUP can be used to find out the results. Download the zip file and extract the contents. Go through the Readme file. Follow along with the provided How To Video file.

### Homework

#### (1) Earthquake response of a four-story building

With the help of MSUP, the earthquake response of a building can be efficiently obtained. Starting with the acceleration history of an earthquake [1], conduct a transient analysis on this four-story building using MSUP, and find out the maximum total deformation history. Check the equivalent stress distribution in the building. Do the components remain linear? Is the MSUP method valid in this case?

#### (2) Diving board

The MSUP method can help us analyze a diving board's vibration efficiently. Follow the Readme file and the video tutorial of model setup and verify that transient MSUP is a linear combination of modal shapes. Download the zip file and extract the contents. Go through the Readme file. Follow along with the provided How To Video file.
