Computer–Aided Design of the Critical Speed of Shafts

A computer aided design software for the analysis of the critical speed of shaft, is developed and presented in this work. The software was designed using the principles of object oriented programming, and implemented with the Microsoft Visual Basic Language. The package was tested on a number of benchmark design problems. The solutions obtained were highly accurate. Also, the software exhibited very high efficiency. To improve on the method of presenting these solutions, graphical features were incorporated. This enhances the ability to visualize results.
