The course includes reading material as well as hands-on software training.
1. Each student must have access to a PC with Windows 2000, XP, or Vista operating system.
2. Each student will receive software programs that perform the following calculations: power spectral density (PSD), Fast Fourier Transforms (FFT), shock response spectrum (SRS), and digital filtering.
3. Students will receive time history data samples so that they can practice using the software programs.
4. Students must have a graphics program such as Axum, EasyPlot, Mathcad, Matlab, Origin, SigmaPlot, etc.
5. Each student may complete the course at his or her own pace. There is no time limit.
6. Students submit homework answers to the instructor, who provides feedback.
Engineers, Technicians, and Managers who must analyze or interpret shock and vibration data or specifications will benefit from this course.
A degree in engineering or technology is helpful but is not required.
The Tuition Fee is $800. Payable by check, money order, or PayPal.
