Software Development of Marine Shaft Torsional Vibration on Martrix VB

This paper discussed the computational model of the ship propeller shafting torsional vibration calculation. And using the analytical method with the help of Matrix VB has developed the corresponding software. It has been demonstrated by the instance that the calculating procedure is accurate, steady and credible. The software interface is friendly and the function is perfect. Beside these, resource expenditure of computer is low and calculating speed is quick. The software is easy to learn and convenient to use. And more, it can be used in all classes of torsional vibration of shafting calculation. General speaking, it is a good tool for the design and calculation of ship shafting and accident analysis. There have a good guarding significance and a good wide applied prospect in improving the efficiency of the design and calculation of ship shafting and the security of ship running.
