【Abstract】 The mechanical and physical phenomenon that torsional vibration is general in mechanical system with rotary parts, and studying characteristic of dynamic sympathetic vibration has important practical value and significance. This paper establishes the calculating model of the shafting multi-branch torsional vibration and develops the corresponding software by VB6.0. The software has friendly interface and perfect function, which is easy to learn and convenient to use. To proof the model and software proper, they are demonstrated by instances. And the test results indicate that they are right and viable. So the software has great value in calculating shafting torsional vibration.更多还原
